Hi, My sons 1993 GC just would not start this morning, all was well just the night before. Anyway, it turns over good, fuel pump is working, there is fuel pressure in the fuel rail, there is spark at the plugs, it seems to me that maybe the injectors are not letting fuel into the intake, but I don't know how to confirm this? Thanks for your time.

Well it turns out that I am getting fuel to the spark plugs, I did pull one to confirm. However the plugs are worn to about a .060 gap. Also my son just did add some gas from a local station that does not have a very high turnover in fuel, may be bad gas in combo with worn plugs???
I'll replace plugs and add some fresh gas and see if that helps.

Well, it must have been a combo of bad gas and worn spark plugs. Replaced spark plugs and it started up. I went ahead and change dist. cap & rotor button too. Don't buy a distributor cap from Federated "Fisher" Auto Parts. Their P.N. FD-175!! What a P.O.S.!!!
Made in China no less. For one thing it is thicker or bigger dia. "out of tolerance" in the terminal towers. This make the one plug wire closest to the intake manifold near impossible to go on. When you do get it on, it is tight against the intake manifold. Oh yea, the screws are crap too, rounded the phillips head out while tightening it up. Yes, I used the right size phillips screwdriver. These screws also have a hex head on them, but the thicker plastic crowded the screw so much, a socket would not even fit over it. I ended up going to AutoZone and bought a Duralast Gold, made in Mexico, but much better quality than the China cap. Yes, when someone makes something in tolerance, it does tend to fit. No problem getting the plug wire on the Duralast Gold cap. The Duralast Gold even came with what looked to be a good quality rotor button too. What ever happen to the days you could go into a Fisher Auto Parts Store and buy the high quality Borg Warner dist. cap?? That's what I went there for. I almost didn't buy it, should have trusted my instinct. You have been WARNED....

Yep, this engine likes the spark plugs changed every 30k miles. Cap and rotor too.
