Default 95 Sl-1 no start


Hello,
The 95 SL1 cranks but will not turn over. A shot of starting fluid kicks it to life for a second, which leads me to believe that it is a fuel problem. there is gas in the tank. how do I check the fuel pump, relay, etc...??

Any suggestions?

Thanks,

Hrmm... First off, when you say cranks, but doesn't turn over, that confuses me a bit. Turning over is cranking to me. Firing or starting is what you want it to do.

OK, that said. The next easy question. When you turn the key to the "ON" position without cranking it, do you hear the fuel pump run?? A slight whining sound.

Default clarification

sorry for confusion,
Cranks = engine turns
Starts = fires up, i.e., ignitiion and combustion sufficient enough to sustain the engine's rotational motion.

I do not hear the fuel pump when the ignition key is turned to the on position, which is why I asked how to check the fuel system.

Is there a FP relay? where is the FP? (tank?) how do I check these?

Thx

I had a similiar problem twice. My engine was basically flooding and wouldn't start. Leave it sit for awhile and it would try to fire at first and then it would just crank and not start. Both times it was because the engine was flooding. It was caused at first by a bad temp sender (the one that screws into the head. It was giving a signal to the computer that the engine was running hot (even when cold) and the computer trys to counter that by dumping more fuel to cool the cylinders (excess unspent fuel absorbs heat and removes it from the engine through the exhaust). This caused flooding. The second time this happened was from corrosion on the same connector that goes to that sensor. Saturn makes a connector kit to cut off the old connector and splice in a new one. So consider this as a possiblity when troubleshooting.

it's because you're missing a cam.

but seriously... it's probably either the CPS of the ECTS. check to see if you have spark. if you do, then your CPS = good and it's probably the latter

CPS = crankshaft position sensor
CTS = coolant temp sensor.

In most vehicles with EFI, when you crank with the accelerator at full throttle, the vehicle enters "Clear flood mode." That shuts off the injection of fuel, and spark, so that the excess fuel will go out the exhaust.

It might be worth trying.

Default solution

Guys, I appreciate the effort, but, your advice was, er, ahh, "lacking"

It was an easy fix. I ASKED How to check the fuel pump and relay. I even said "I cannot hear the fuel pump come on" Once I go ahold of a cheap manual, I buypassed the fuel pump relay with a paperclip, and Viola'! She starts up like nothing is wrong.

In this year/make/model The AC relay is the same part as the FP relay, so if you are stuck on the road due to a FP relay going bad, you can plug the AC relay in and you are good to go. I did this and it got me to the parts store to buy a 14 dollar FP relay (cheap).

That was a while ago, no problems since then.

Now you know "the rest of the story"
