Hey I have an 89 12 valve in my ramcharger it is bone stock other than turning the injection pump up a bit, so it blew the fuel pump and all the injector lines and inlet and return lines on the motor so I replaced all the lines on the motor and the fuel pump and it runs perfect in park or neutral but in drive or reverse it misfires until it gets to wide open throttle then it clears out, I’ve been trying to figure it out for a week now and I’ve tried bleeding all the lines and everything so does anyone have any ideas on what it could be? Thank you much appreciated

 

I beleive you have a timing issue?

 

After the 6th "and", followed by a "but" and a "then" without any punctuation, I got confused.
Maybe he has a timing issue, but he surely has an issue clearly explaining his problem.

How did you tune up the pump? What exactly did you tune?

How did the fuel pump and ALL the lines on the motor blow up, as you say?

Does the engine emit a whitish smoke?
