Question about Cars & Trucks
I need to know what fuel injectors will work from what throttle bodies ive got a 1990 chevy s10 2.5 need to know what vehicles and engines to get a used one to try
This might sound like it's not much help, but I've found out that many local junk yards have cross reference systems for engines,Transmissions, and many other parts. I would try one of them. However; since the "cash for clunkers" fiasco there are fewer and fewer older models to find for parts! Peace. God bless.

Make sure that you're getting spark. A very common thing on these engines are coils going bad. If you can verify spark, check to make sure you have an injector pulse. As you rotate the engine, look inside of the throttle body and make sure that you see fuel pulsing into the engine. You can still have good pressure but you don't have an injector pulse, the fuel still cant get into the engine. You can use a test light as well to test for an injector pulse. One wire going to the injector will have constant power and the other will blink when the engie is rolled over. Does it start if you spray starting fluid into the throttle body? If it does, it's a fuel delivery problem. Again be sure you have spark from coil to distributor and plugs. You can remove the ignition module and take it to NAPA and they have a module tester. Have them test the module several times not just once. This will eliminate the possibilites of an intermitted problem. Let me know how it does. email@example.com

the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up

ecm does control but is also based on input from the Throttle position senser. unplug the TPS and try again. Also make sure the ECM and engine grounds are good
