Project El Taco...1990 BII

I have found another thread where someone put a SOHC in their 94 explorer:
http://www.explorerforum.com/forums//showthread.php?t=159001

I want to do the same to my 93 ranger. i have the SOHC engine in my garage, i just need to find a fuel rail from a 97 SOHC.

I saw this thread when I started the SOHC swap, but the funny thing about it is it never shows the truck running, or even the engine in the vehicle. What he said about the details convinces me that he at least had the engine in, but nothing proves that he actually had it running. He never went into detail about the injectors (at least from what I remember), Nor did he mention hood clearance issues and lots of other stuff. From what he wrote in his thread, I could have written before I started working on mine again.

Its nothing against him, I just wanna see some video or at least pictures of his setup.

Im gonna get my ass outside and get plugging away at this thing, I wanna hear it run.

Fair enough... I want to see yours run! mostly because I want to do the same thing. I have a 2005 ranger SOHC 4.0L in the garage.

Well I just about have it buttoned up, its got fluids, turned it over and Im not getting any fuel pump action. Now I had this problem before it got parked, in fact it was the reason it got parked, so Im sure, being that its a totally different fuel pump relay, that it has to be the pump. Luckily I have a spare 110lph pump that was going to go on my mustang when I had it, So tomorrow Ill drop the tank and install that and a new sending unit. The good news is that it has spark and turns over beautifully, I sprayed some Carb cleaner down the tube and it popped and stuttered when I turned it over.

Im also having problems with the neutral saftey switch or something, because it doesnt want to turn over at the key, but I can get it to turn over by jumping the relay. The little wire that provides the signal isnt giving me anything when the key is turned. Im convinced its got to be the saftey switch deal, so Ill investigate that further.

Tomorrow that plan is to:
Drop the tank/install FP
Figure out the safety switch deal
start the engine
Bleed the brakes
Bleed the clutch
Run exhaust
Put the plates on and drive it

more tomorrow...

Nice work. I can't wait to see a video of this running.

IIRC, You changed the top plate of the transmission, put the 94 on the 2006? could this be part of the problem with the safety switch?


good luck.

ive got a 85 ranger body on a 95 explorer frame with a 01 sohc 4.0 motor project. you all are allot closer to starting then i am. im just starting my project

 

[RacinNdrummin]

It runs!!!!!!


Helps when you have the computer and inertia switch hooked up...(It was a long day yesterday)

Video later...

This thing is just weird, the fuel pump was working just fine this afternoon, and now it just stopped working. Im getting power all the way back to the pump and is grounding just fine, but the pump just isnt working now. Tomorrow im going to pull out the sender and pump and find out whats up.

On another note, I was out at the JY today and I found a Y-pipe from an explorer that somebody cut the cat out of and I can use that to cut some some time out of fabbing the exhaust.

Also, for some reason the start signal is split in btween the fire wall and the relay, so thats why it wasnt starting with the key. I just tapped off the wire out of the round connector, and it turns over just fine with the key now.

Just a few bugs to work out tomorrow and it should be driveable, Ill have video as soon as I have fuel again.

Video as promised....

Had to swap out the fuel pump...

Here is a few pics after I turned it around and after the engine bay was together:

Tomorrow after work, I plan to get the exhaust done, get the hood on, and get the front bumper on as well as do the blinker Mod as im not putting on the lower valance and blinkers.

Ill get some more videos when I have it roadable as well as a sound clip with the thrush.

sweet!

Im having a little trouble with the engine now. When I first started it the other night, it fired up fine and idled a little rough, but caught itself and idled fine. Now after finishing everything up under the hood, I have a high idle (as seen in the video). I had noticed when I started it yesterday, I had forgot to plug the TPS and IAC in, so I plugged them in. The thing still idled high. No change with the IAC or the TPS unplugged, and I checked for vacuum leaks with brakeclean. If I unplug I the MAF sensor, It idles down, a little rough, but at a normal RPM. The catch is, I changed out the MAF sensor, and it still idles high. I took it around the block and it runs like crap, backfiring out of the exhaust and stuff.

I unplugged the battery tonight, so tomorrow Ill plug it back in and see if it makes a difference.

Anybody have any Idea's?

 

[shawn.m]

hows your grounds?

 

[cargs]

Aside from the grounds above; the first things that comes to mind are the O2 sensors, injectors, and MAF. check over your wiring harness, make sure there isn't any loose or bad connectors.

can you list the sensors used,what year are they from?

are the injectors from the t-bird the same size as the 94?

can you pull any of the basic codes from the computer? (I know its only OBDI).

 

[RacinNdrummin]

I checked the harness, even with it running, and there is no bad connections. O2 sensor is Fairly new and nothing changes whether its plugged in or not. The injectors I "rebuilt" (orings, filters, pintle caps, and a good cleaning) and are for sure 19lb injectors just like a 4.0 OHV ran stock. The MAF is from a 91 explorer and has a 90 part number. The IAC is either off of the 2.9 or my old 5.0, either way, the computer adjusts the IAC with a pulsewidth based on displacement, so it really doesnt matter all that much, different IACs with work on different engines. The IAT and CLT are brand new 90 ranger parts. The FPR is a 270KPA(~39psi) unit.

There is no CEL so I assume there is no codes.

Im going to see if letting the computer drain does anything.

 

[RacinNdrummin]

I might have gotten it figured out.

The backfiring was from 2 spark plug wires being crossed at the coil pack. I made a block off plate for the IAC just to see what it would do and now it doesnt want to idle, so that leads me to believe that contrary to what I thought, there is a difference in the IAC's. I know in Megasquirt, you have to set the frequency of the valve and the pulsewidth, so I would bet money that the 4.0 and 2.9 IAC's have different frequencies they operate off of.

My plan is to get a 4.0 IAC this afternoon and try it out.

AND MAN DOES THIS THING HAUL ASS!!! I took it around the block after fixing the wires, and the thing wants to spin my 30" bighorns like they are cheap street radials. If I get it fixed today, Ill get some video up later.
