My 93 sputters and dies NEED HELP
Hi,
I have a n issue with my 93 ZR1. A few weeks ago my ZR-1 started to die when she was cold and I had to keep her on RPMS to keep her running. Now the issue is worse and she runs rougher and dies directly after starting. Has anyone had similar problems and may knows where I should start searching for the problem? Thanks you all! |

Check to see if one of the rubber hoses disconnected from one of the fuel pumps. Pull the fuel pump assembly from the tank and check, takes less than 30 minutes. That was the problem with mine. A new stainless steel clamp fixed the problem.

My situation was this. Car would start up fine, run great for two minutes, and then stumble. It was the oxygen sensors.

Hi Guys! Thanks for your input.
I found the Problem. It was the vaccum hose that was detached from the MAP Sensor. |

Re: My 93 sputters and dies NEED HELP
Cause: Releasing ignition key too soon from start position.
Cure: Hold key in start position just a second longer Sent from my iPhone using ZR-1 Net Registry
