Hello,
I know this has been discussed many times before. I’ve searched for weeks and couldn’t find anything semi related to my issue.
1995 Mustang GT
97 explorer engine
Anderson n-41 cam
75mm throttle body
New fuel tank, sending unit, new fuel tank harness
Aeromotive 340 pump
New dizzy, 3 of them actually
New iac
New tps
My issue is the car just decides not to start, 38lbs at rail. I unplug the tps and it will start then dies. Plug TPS back in and starts.
I thought I fixed this issue when I replaced the TPS and the car actually cold started great and open loop would act dumb with idle then back to doing well.
I had an exhaust leak. Fixed that and now it’s back to not starting again.
Done base idle reset with it idling around 750ish iac unplugged.
Turn car off let it sit for two minutes, plugged iac in. Went to start with accessories on for 2 minutes. Same outcome doesn’t fire just cranks. Unplug TPS and it will fire off.
I’m totally confused at this point as I’ve tested tps signal and so on.
I guess my question is where should I go? Bad computer? Bad ccrm?
Any test I can do to see if I can isolate what the issue is?
At some point I will go standalone ECU, however my thought is if it’s something in the wiring the new ecu will not help. Maybe I’m in left field or have no idea what I’m talking about.
I would really like to get this sorted out so I can actually drive the car some without the fear of it not starting somewhere. Take my kids for a ride in it. It needs to be safe before I can do that.
Please feel free to chime in with suggestions positive or negative lol. I have tough skin.
Thank you everyone in advance for the responses.
