We had it running 2 yrs ago, then while at idle it runs out of gas. Ended up putting in 2 new fuel pumps, fuel filter, new gas, and car refuses to start.
All cylinders have spark, but may be a weaker spark, can't tell for sure. Also put fuel pressure gauge on and it was I believe 50-55 lbs. starter cranks ok.
I am not sure if fuel getting into cylinders.
I had a local mechanic look at it, but he didn't seem too smart.
The red car will start with bypassing Or jumping a purple wire under the hood.
BUT, when I test drive, it has maybe 100 hp, runs smooth, but can barely get to speed limit going downhill.
Any ideas ? Where could I find a good ZR-1 mechanic in Alberta ?
Thanks,

Black car:
If you have fuel pressure of 50+, you should not be suspicious of no fuel in cylinders, unless you sucked up enough crud to clog everything after where you have pressure.
You need to see if any injector is spraying fuel.
My guess is they are not.
Pull a plug or two, and report back.
Red car:
You have a failed clutch switch or open in the circuit which you get around by jumping.
There are a number of fixes on here, just do a search.
As for the100 hp, sure sounds like your fuel pump problem from the other car has found its way to this one.
Make sure both are working by going through the troubleshooting section of the FSM.
Again, let us know what you find, if pumps are good you may need to check the injectors.
