Hi, I’m Ron and I can help you.I have been in the auto repair business with my own shops since 1975 and also teachautomotive repair. I am confident we can resolve your problem together. Pleaseunderstand that I don't know your skill level. In most cases when you have a problemwith the way the vehicle performs, specialized tooling is required to acquire computerdata/information or engine testing results. We didn’t build these complicated vehicles; wejust diagnose and fix them. Also understand that I can't see, smell, hear, or touch thevehicle either, so it may take a few replies to get to satisfactory results. I am also going todirect you with the fastest, easiest and most common things to check first. Please bepatient and permit me to do what I do best.I also try to give all of the information you may need, expecting a “positive rating” inreturn. I will also continue assisting you after you have rated me, if necessary. If thereis any reason I cannot get a positive rating, please let me know why “in advance”, so Ican go another direction for you. I am sorry you’re having this problem; I’ll help youthrough it. Frsrt check to be sure there is no spark at the plugs when cranking it, then check fuel pressure with a gauge. Just hearing it run isn't good enough.Thanks, Ron

I have fuel pressure I have no spark

Okay, then check for power from the ignition switch to the module. A scan tool would be of great help right now if you have one. Otherwise, our results may not be accurate.Thanks again, and please don't forget to rate me and keep this link in case you need me again later on.Ron

Car is early 96 my scanner is on 2 it won't work with this car
Expert:  rpmdiag replied 1 year ago.
Do you have a scan tool or a lab scope? We need to test the crank sensor inputs and outputs. What is the fuel pressure reading you have?Ron
Customer: replied 1 year ago.
My scan tool will not connect with this car
Expert:  rpmdiag replied 1 year ago.
Okay, then we need to get one that does. We need information from the computer. We don't want to make any expensive guesses with this. Thanks again, Ron
