New to the forum i have a 97 neon SOHC number 1&2 fuel injectors not fireing but yet 3&4 are working properly car will startr but runs liek complete S*** checked my ground all was fine, hooked up a spare fuel rail and injectors same problem.... if any one has some advice for me would be greatly appreciated considering this is my daily driver and im out a vehicle right now! THANKS

 

Check for the power source wires for 12+ volts and that it will power a test light. If not (hopefull this is the porblems side try and see if the splice points are boken not allowing enough power to got through. If so reattatch by having them soldered in correctly and reweather sealed. If it is the ground side one of 2 problems. Open in the ground wire or BAD PCM. You should have a fluctuting ground if not you need to check the wires back to the PCM for less than 5 Ohms but lower is MUCH better and normal. If it is and you still ge no ground then it is the PCM. If you have access to noid lights that is a quick check but not very thorough as the require VERY LITTLE power to operate. If wiring check out then you probably lost an injector or 2 in this case. They should be 10-16 Ohms.

 

Problem fixed, seemed too be as simple as a bad PCM got a new one yesterday worked just perfectly thanks for the help
