i have a 1987 olds cutlass wagon. v6 not sure what size. it wont start, it has plenty of spark and i spray starting fluid in the (throttel body?). its multiport fuel injected. it cranks and cranks and cranks without even a burp. i checked fuses, i can hear the fuel pump, and i am stumped, we drove it the day before with no problems, next morning it was dead. the only thing i can figure is it something electrical i dont know about. im clueless.

The gas gauge my be wrong. Make sure there is gas in the tank.

That said, start by checking for fuel pressure. There is a port on the injector supply manifold to connect a pressure gauge.

If that's OK, you need to pull the codes from the computer and proceed from there.

Post back with what you find.

Doc here,

Check the Fuse Panel for the Following Fuses, ECM, ECU, INJ, CC Sensor.

Be sure these are Good, (test them with a DVOM, don't eyeball them) Replace any that are bad.

It's most likely in the Injector line, as the engine won't fire bottle fed (start fluid) if the Injectors aren't pulsing with the reference pulse. you just spray it in the intake tube, and t goes nowhere...

Do you have a MAF sensor? check that too.

fuses where a first thougt, i eyeballed them but will test with tester. can you go more into detail as to why spraying spray in the intake wouldnt work? kinda clueless on multi port fuel injection. im used to throttel body injection and carbs.

and what do you mean by "injector line?" the fuel line? or fuel pump?

Finaly after getting it into my buddys garage, and 1 fuel pump later, we figured it out to be a timing gear thanks for all the help.

Doc here,

Sorry I didn't get back to you before the fix..I lost the post in cyberspace..and I don't often do that..

Glad to hear you did finally get it! Fine job!

And thanks for posting back the fix..It may just help the next guy out..

Was that a set of gears or a belt on that car? Just curious..

Hey, just curious.

How did the engine skip cam timing if it was running fine when you shut down?
Or did you rev the piss out of it before shutting down?

It has timing gears, heres the fun part, the stock ones are aluminum core with plastic like gears on the cam. Best I can figure is there where cracks in the plastic and the next morning when we went to start it the stress of doing so striped them out. It was very cold that night and the fragments I found in the oil pan where very brittle. Another thing that probably contributed to the problem was the timing dampener was worn to nothing. O-yea, this car has a 3.8v6 just for reference.

THANKS AGAIN FOR ALL THE HELP!
