i have an 1988 toy. truck 4x4, which has a 22re in it. fresh rebuild with about 3000 miles. it wont stay running. it will fire on first crank after sitting for a couple minutes, and die instantly. then all it will do is crank over. i have done basics. plug wires, fuses, check for fuel at throttle body, checked volts here and there. maybe a little low at ignighter mounted on coil. same as spark, a tad faint. anybody have any thoughts.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment. If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money. Every engine requires spark, fuel and compression to run. That's what we have to look for. These are the basics that need to be tested and will give us the info required to isolate a cause. 1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on. 2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on. 3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off. 4) If all of these things check good, then you would need to do a complete compression test. Once you have determined which of these functions has dropped out, you will know which system is having the problem. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

No, it's a fuel injected engine. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

It was made with a carb depending on point of destination. Here's the carb that might have been used on this............. Tom
