Wont start when hot, But runs great.

[clark53214]

Ever sence I changed the cap and rotor I been having nothing but trouble it My 2.9 v6. I now have it running but will only runs for about 15 to 20 mins. It runs great then it almost dies then it dies and wont start. The only code I get is 18 and that code should only come up when it is running. I was looking at some of the wires to see if there got wet form the powerstering pump. (the cap came of) . Thats when it alosted died. I left the wires along and it died 30 sec. later. Im thinking its a loose wire buy the coil. Did I say it runs great before!

code 18, idm code .. Ignition diagnostic monitor (IDM)

heat related ??

ign module. TFI ? good chance

What is a SPOUT?

It also said in the book thank the SPOUT could be grounding out. I saw a fuesable link in that area where it got wet and it was a red with a green strip on it. I look in the book and it said it hot in run. I think it coming for the coil.I was thinking on replacing that fuseable link before the IDM, but what is a SPOUT. I can't find anything in the book on or what it is. I used to work on chevy so the ford thing is new to me. I also think my brother just replace the IDM about a year ago and it hasn't been driven that much until now because we had to put a new rear end ( 7.5 to 8.8).

 

[turboranger2.3]

SPOUT. is spark out put . ecm controlled timing

with spout un- plugged, you get base timing

we set timing with spout un-plugged.

shorted spout very un-likely.

ign on, is there power at coil + with test light.

if so now, test coil - with test light. crank motor, does test light flash.


if it flashes. TIF module is working, no spark. its you coil. FOLLOW.

IDM is just a diagnostic tool, to help . diagnos ign issues.( frequency)

test fuseable link with test light.

ITS a fuze. power in power out. to the circuit.

 

[clark53214]

I Checked all fuseable links and still nothing. IThink it might be relay but I dont remeber how to check it. I have power to the relay but some time and the last couple of time there wasnt. I don know if its the relay or the pickup coil. I dont know how to test them. I do know I did have power to the pickup coil.

 

[turboranger2.3]

Go to ignition coil. -- check at POS. --At ign. coil..--- Ign on . with test light. if power

then----- put-------test light-------at -neg.-- --at ign coil----with test light.


crank motor----does test light flash. dim flashes. not real bright


If no flash. probably TFI module

 

[clark53214]

I put a new coil, new module, new cap, new wires, and plugs. The power doesnt seem to leave the eec relay. I was going to jump the relay to the coil side to see if it starts. I think thats how you can tell if its bad. I had a mec. show me years ago but dont remeber how.I was going to put a new rotor but it didnt start. When I put the old one in the truck started right up. It ran great I drove it around and when I when to go back to the place I kept it,and it stalled a stop sign. I tried to get it running then put couldnt. I disconceted the battery and let it sit for 2 days. On the 2nd day I reconceted the battery and it started right up. I drove it back ( runnig a couple of stops signs) and let it sit runnig to see if it would do it again. After the 15 to 20 mins it died and hasnt started. Thats when I put the new module in and checked all the fuseable links and it comes down to were I am. I was going to get a good cap and rotor set before checkin the relay. I know you are to out in new cap, rotor, and plugs but the rotor that I had in there had trouble starting and it ran rough. The cap and rotor are autozone crap. Im looking to buy motorcraft or better.

The spout plug is not a fuse, it is a little grey fuselike link inline with your electronic wiring, but you shouldnt have a spout plug unless your running DIS system. Distributerless ignition system, or soemthing very similar. Basically electronic timing. When the spout is unplugged the timing defaults to a base timing of 10 degrees. this must be unplugged when adjusting the timing belt or chain or gerbil whatever your truck came with. Once the base time is set then you plug the spout back in and the computer fine tunes it. Your distributer system wont have a spout plug. You have to turn the distributer cap by hand and adjust things i believe.


KEEP IT SIMPLE If you changed one thing then bad things happened the onething you changed is most likely your problem. Proll an installation error(such as adjusting the distributor cap

 

[turboranger2.3]

EEC pwr. relay, feed Injectors. WITH IGN ON IS THERE POWER
AT INJECTORS.
IDLE SPEED CONTROT
EGR VAUCUM REG.
and a few others
so check power there , if power eec is good.



on any no START

THE stratergy , you decide is it SPARK(electrical)


OR FUEL

WHEN IT HAPPENS . DID YOU CHECK FOR SPARK
what made you decide to change those parts.


did you find no spark??


If you have spark. ----then check fuel


From what you told us it didnt start. that mean nothing.


100 issues can cause a no start.

you narrow it down by 50% by deciding if it SPARK OR FUEL.


LET SAW, IT HAS SPARK. ARE YOU GOING TO CHANGE CAP AND ROTOR

OR LOOK AT FUEL.

Find out which one it is.DID you check for spark??

I had this happen on my buddies Ranger when I put a new cap and rotor on it. It ran fine at an idle while it was cold, but gradually ran worse as the rpm's and temperature went up. It turns out I had two of the plug wires wrong. Have you checked to make sure all of the plug wires are in the correct position? There is a pic at the bottom of the 2.9 page in the tech library you can use for reference.

I remember cursing Ford throughout the tune-up for doing pulling a "Chevy" by putting that damn dizzy in the back. That was a PITA tune up.

but you shouldnt have a spout plug unless your running DIS system

I'm 99.9% sure my buddies 89 Ranger with a 2.9 liter has a spout connector. In fact, I would say it would be more likely you DIDN'T have a spout if it was DIS. The purpose of the spout is to help you time the vehicle, and seeing how you can't really time a DIS, I would say it's LESS likely here.

 

[t120r]

I had the exact same problem you are saying. Check the exhaust manifolds to see if there is a wire burned. On my '92 there was a harness that comes in close contact with the drivers side manifold. It never even threw a code. Go figure.

 

[CountryBoy704]

if it started when you changed the wires, cap and rotor i would go back and make sure the wires are right, if the cylinders are firing out of order it can cause things like this follow shane96ranger's link ^^ if all the wires are right it might be a timing issue, any haynes or chiltons manual can tell you how to check and adjust timing

 

[CountryBoy704]

some stuff from the tech library

TFI Module:
Your Ranger/Bronco II is stalling/dieing or sputtering when hot but runs when it cools off. This can be caused by a faulty TFI and the biggest culprits are heat. Another culprit can be a wire grounding out. Problematic TFI's can give off codes 14 (PIP) and 18 (SPOUT).

Exactly the opposite. My 1992 ranger 2.3 and my 1993 ranger are DIS (distributorLESS Ignition System. The distributorless system needs the spout plug, when you unplug the spout the timing retards to a factory setting of 10*. At 10* you adjust all your timing issues and when you are done and everything is the way it is supposed to be you plug in the spout and the computer advances to timing to the proper settings based on what the computer reads in the engine.

The distributor type system will not have a spout plug because you simply turn the distributor clockwise or counter to advance or retard the timing by hand.

If your 2.9 is distributorless then is has the spout plug, If it is the distributor style then it won't.

Please don't imply my head is up my ass by telling me I'm "guessing". I didn't belittle your statement. We are both right, Ford used the SPOUT on DIS and distributor engines. The fact of the matter is, the 2.9 has a spout, and not a single 2.9 came with DIS. I've worked on countless Mustangs with a spout connector and distributor, so I knew for a fact when I typed it you were incorrect about the distributor not having spout. Let me change my wording to, the spout is less useful on a DIS. How do you adjust the timing on a 4.0?

EDIT: Sorry to the OP, I just hate it when someone implies I'm throwing darts at answers.
