Hello iluvemy1976chevy

Does the start problem happen when the engine is hot or cold ? Some 1994 Chevy s10 's with throttle body injection have a hard start problem when the engine gets hot. There are also a few other bugs that you should be aware of :

Oil leaks: A tough-to-find leak is located in the oil filter adapter on V-6 engines. The solution is a new O-ring, but access is difficult. High-mileage 2.8L V-6 engines can leak badly at the front of the intake manifold. New gaskets are the proper fix, and silicone sealant is the quick fix.

Engine knock: The 4.3L V-6 can have knock (especially at startup) that's eliminated by using an oil filter with a check valve. Severe knock requires a revised PROM for the computer.

Loose fan: Several different engines with and without A/C had recalls for poor fan blade rivets.

Misfire, rough idle: Carbon buildup can cause the EGR valve to stick in open position and cause a rough idle.

Serpentine belt squeal: V-6 engines with the serpentine belt system can squeal loudly due to a worn idler pulley or tensioner. A new pulley and belt should fix the problem.

Loose fan: Several different engines with and without A/C had recalls for poor fan blade rivets.

Misfire, rough idle: Carbon buildup can cause the EGR valve to stick in open position and cause a rough idle.

Fuel sender seal: There was a recall for a bad fuel tank sender seal, which could cause gas leaks.

Seatbelt problems: There were recalls for '91-'93 rear seatbelt defects, such as sticky latches. Some '94-'97 webbing was substandard.

If you encounter any of the problems mentioned you'll know what to look for .

hope this helps ..Good luck !

After reading this I began to wonder if a throttle posistion sensor that is begining to wear could cause this by not giving a good signal until it is moved.
Im not really offering this as a answer but more of a question that maybe someone could elaborate on.

Perform a fuel pressure test.
