1990 ZR1 problems - ZR-1 Net Registry Forums

Randall1 · 01-24-2008

Hello all, I have a 1990 ZR1 with 32k miles on it that has been in storage for about a year. I have started the car every month and wamed it up. The last time I tried starting the car it stumbled and backfired and the SES light stays on. The car did start and runs but not with the power it normally has. I checked the vacuum line in the back (hard to get to} and made sure it was tight. Checked the plugs and they look good and when I turn the key on I here the vacuum pump go on and then turn off like it should. I bought a fuel pressure gage today and a new fuel filter and will check pressure and change the filter tomorrow. I was just wondering if any of you folks have any ideas before I tear into the car. The engine intimidates me a little but I am pretty handy with a wrench.

Thanks,
Randall
