No Start - 88 2.9L

Final update… somehow now it fires off of ether. So it’s a fuel problem. Sorry about all the back and forth headache between spark and fuel. It’s officially fuel. Now to try the fuel pressure regulator, and if that’s not it then I’m going to guess injectors would be next on the line.

Do you have pressure at the schraeder valve on the fuel rail?

How much?

 

[johndough]

Invest in a fuel pressure tester.

The regulator wont stop it from getting fuel. When those fail it usually overfeeds it and allows to much fuel.

Buy/rent a tester. Test it with key on/engine off (KOEO)...should read in the 40psi neighboorhood.

If you have 40psi you can pull the coil wire and crank the engine. Then pull the plugs one by one and see which ones are soaked in fuel....if any. That will tell you which if any injectors arnt fireing off. Id pull 2 then recrank to make sure gas dont evaporate in the cylinder

Report back.

Going to grab one now, so when priming with the engine off it’ll still read 40PSI?

Somewhere thereabouts. 40 is spec. Anywhere above 35 or 36 youre probably safe.

Well shoot. No pressure at all at the frame rail. Great, so it seems like I should go backtrack everything I just replaced? Tank, in tank pump, canister filter, frame rail pump, and the next filter up.

Well. You have an answer. Which is good.

So no pressure at the rail under the hood?

Pump is running correct?

Pull the line off the canister. The one that goes from the tank to the canister, turn the key on and see if fuel runs out. Then youll know the intank is working.

The high pressure pump youll obviously hear.

Make sure the fuel filter isnt installed backwards...the arrow should point toward engine.

Also make sure nothings kinked.

If everything checks out theres no reason you should have nothing at the fuel rail and either the gauge youre using is screwy or ya botched the test lol

You have a few answers now, I gotta add one more tho, that distributor isn't 180 is it?

Will do tomorrow. So if my brand new in tank pump isn’t working, what do I check? Only thing I can think is I didn’t clean the connector for the pump. Maybe I can find a diagram of the connector and see which of the prongs on the connector I could take a multimeter to to find out if it’s giving 12V.

Connections...or possibly a bad off the shelf pump. Part quality the last 3 or 4 years has been total garbage

Tested all the lines, I had fuel coming out of the lines to the canister, fuel coming out of the frame rail pump, and the filter is facing the right way. After priming however many times and trying to start, I think the starter solenoid’s shot. Still wasn’t getting any pressure up to the top of the motor for it to fire up before that happened. I really don’t want to send it to anyone else as I feel it’s not that hard of a fix and I enjoy learning this stuff.

The solenoid only works to engage the starter...priming it by turning key on shouldnt involve it

 

[Josh B]

Pull the starter and use some jumper cables off the battery. It's really simple. a ground and a hot brings it all into play (IF it's working correctly) Wearing good gloves might mot be a bad idea if you've never checked one before

 

[Dustin_89BII]

Anything to report on this issue? I'm so curious... And did you check if the distributor was 180 degrees out like the Junkie mentioned? That just happened to me, lol.

That shouldn't matter with zero fuel pressure
