Hot Start Problems!!
 

I have a 90 7mgte that will start from cold will restart straight away when hot but if left for a couple of minutes will not start:eek3:until fully cold. There seems to be no signal to the injectors, no power to fuel pump but when bridged will run,all temp sensors work,cps works, even rewired the cps terminals, efi relay works, main circuit relay works.
Any suggestions??:dunno: please not the ecu!!

Pull codes.

Find a baby sitter.

Buy a honda or a nissan.

But pull the codes 1st.

no error codes just done full pin check on ecu still will not start:crazy:

If the fuel pump is the only thing loosing power then the fuel pump resistor pack or relay (mounted to the passenger side fender) may have failed. Try bypassing them, starting with the resistor pack.

Break out the volt meter and start metering any and everything.
Double check all of it.

You'll track it down with minimal effort.

LOL...., did you price hondas and nissans yet??:dance:

Fuel pump relay???

Have you checked all of your sensors?

sorted problem ecu has fault failing under load thanks to everyone with suggestions by the way i run a cosworth sierra would not consider a honda etc

Cool. I wasn't serious about the honda.
