89 5.0 Mustang

Alright so once again im on trying to figure out my crank no start issue.
heres the deal for everyone that does not know.

95 Cobra
Cranks and Cranks and Cranks.
This is an intermittent problem.
SOmetimes is will just start right up all day and others it will give me issues.
Doesnt matter if its hot cold been running or its a cold start.
I have basically narrowed it down to being ignition related because i have fuel pressure when its having the problem and when its not.
I have replaced
Plugs
Wires
Cap
Rotor
Coil
Ignition Control Module
Constang Control Relay Module
Fuel Pump a while back
and same with the filter.


There is no issue with the car when it is running.
I did notice the injectors were a little loose in the hole, like they can spin back in forth kinda easily.

So my next steps are doing a noid light test
and replacing the hall effect sensor.

please give me some other ideas i can go to.

Thanks
Steve

I just bought my cobra a couple days ago and it does the same thing, except to get it to start you have to pump the gas(and it's fuel injected...i know it doesn't make sence). I have replaced the same things you did so far and I plan on double checking the TPS and timing to see where those are set at.

well i thought it would be the tps early on but i have no other reasons for it to be the tps. My idle doesnt soar and go all funky.
Let me know if that helps wat u do and all

Check of codes. When it wont start check to see if you have spark. Also like you said use the noid to see if you have injector pulse.
Pumping the throttle on a fuel injected vehicle will not do anything.

Usually, it's not supposed to do anything. But you absolutely can NOT start the car without pushing the throttle in and out a couple times. Hence why I thought it would be the TPS.

Start by ID'ing what is missing for the engine to start..... spark, fuel?... don't keep on throwing $$ at the problem...... How to Solve an EFI No Start ..... LUK

well a week or 2 ago it was doing it and and i took off a wire to see if i do have spark.
and from wat it looked like i did not have spark at that time cause we probably cranked for a solid 5 to 10 secs and that is more then enough time to see if it would spark and it didnt.
So i guess im also looking at an intermittent spark too.

Yea i have done that and really narrowed it down to be only spark. When it was having the issue i disconnected the mass air and it had no dif. So air is not the issue. Fuel Press is perfect when the problem is happening and when its not. When the car is on and running it runs perfect.

have you checked for broken or loose wires going to your coil ... probly have just trying to mention the small things

89 5.0 Mustang

well none of them are cracked that i can see but the ones inside the black wrapping i havent seen.
But if they were broken or cracked wouldnt that cause a problem when running too?

ive seen times when there is a wire broke and the symptom will come and go as the car is jarred around while driving ... doesnt happen very often but it does happen
