Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
In order for the engine to start and run you need good spark, proper fuel pressure, injector pulse and good compression, if you are sure you have good spark as well as good fuel pressure and injector pulse then the next steps would be check the engine compression. Post back with the results and we can work from there to get this resolved for you.

Not a compression problem. 160-170 per hole
Expert:  Ron replied 2 years ago.
Okay so you are saying you have good compression as well as injector pulse and proper fule pressure and good spark , correct? If that is the cases the engine should start and run right?

Okay one other thing that you may want to check is to make sure the exhaust is not restricted. If it's plugged off it would also cause a no start.

Exhaust is less than a year old. Ran fine friday no start monday
Expert:  Ron replied 2 years ago.
Well something is not making any sense here for sure, are you sure you have injector pulse ?
Customer: replied 2 years ago.
Yes put noids on 1 & 2 since it fires 1&3 and 2&4 at the same time and got lights on both
Expert:  Ron replied 2 years ago.
Well I'm not sure what to advise you on at this point, you say you have good spark, injector pulse , proper fuel pressure and good compression. The engine should start if that is the case. I can open the question back up for you in hopes someone else has some new ideas if you would like.

Expert:  Ron replied 2 years ago.
