My surban want turn over. I have replaced, Ignition Control Mod, Ignition Coil, distributer cap, pick up coil, Rotor Ingtion, Timin Chain, Fuel Filter and Battery. Had the fuel pump check and was told I was geeting enough fuel. Also had a code comback P1351, which is the code for Ignition Control Mod. Si with all these part replaced could it be my computer that is out.I was told the ECM may need to be replaced. Any responce would be helpful.

thanks

It does not crank?

Or

It does crank and does not start?

"Crank" meaning the engine is spinning over but not starting.

All the parts changing did you check for spark
do a spark test and check if the injector pulse
check TPS volts make sure its not in flood mode

Okay thanks for the feedback. I will look into tomorrow when I get home. I'm think he didn't put the wires on correct now. But I did replaced the dist. Cap and pick up coil already. I'm thinkin he just put the plug wires on wrong. But if he didn't beside the TPS, what else can I look at.

Also, I remember last week. When I pulled up to a red light or stop sign I noticed on my gauges, the oil pressure and battery gauges would drop off. Then when I started to move again they would rise up. On friday night comin from fishing at one stop when I came to a intersection the batter gauge drop dwon so much that all my light when dim. Then the next day I start havin this issue with my truck. Could this have something to do with they way my truck is actin.I had the alternator check and it passed several times

I replaced the coil and I had two wires in wrong. The number 2 and 4 wasn't in the correct firin order and I found out the number 8 wasn't all the way on. I had it towed to a shop today and the dude told me it was the feul pump went out. After I sprayed the starter fluid in it. It never started, so could the fuel pump be out or is he tryin to pull as fast on on me
