Puzzling Problem

[stephenw22]

My turbo wagon has been sitting for a while, and I'm trying to get it back into shape, but it won't run.

 

I have spark, and air, but the fuel isn't getting to the cylinders. If I dribble some gas into the throttle body by hand, the engine runs (poorly, but runs). I'm getting no error codes.

 

No fuses are blown. When I hook up the green connectors, the fuel pump cycles on and off, and is working fine. Under the hood, it sounds like the fuel regulator is doing its job. I forgot to check the fusible links, though. Also, I didn't have a meter with me to check for voltage at the injectors.

 

I've never had to work on fuel injection stuff before - what could be wrong?

Is there a fusible link that feeds to the injectors?

Do all of the wires feed from the same cable?

Could have all of the wires been worn through?

Is it something related to the injectors(tps or something)?

Some kind of other relay or switch?

 

Thanks!

Could it be clogged injectors?

I would check the fuel pressure at the throttle body with a guage. If you dont have a guage, you could eyeball it by shooting the hose into a bottle.

 

My guess is that pressure is either low, or non-existant. It could easily be a clogged fuel filter. I would replace that anyway, regardless of what the problem ends up being. The car has sat a while, and attempting to start it could have stirred up some crud, which now resides in the filter.

 

Since the fuel pump cycles on, you can eliminate electrical as a potential problem. It could operational but weak. This also makes sense if the car sat for a long time.

 

It's probably the fuel pump, but do your toubleshooting first.

 

good luck, John
