88 IROC BOB

Since I bought the car 6 years ago it has always had a hard start problem. Also the cooling fan runs as soon as you turn the key to "on" and run constantly.
After 6 years of owning this car today I noticed that there is a wire which is supposed to be connected to a sensor on the passenger side of the block, is grounded which is probably why the fans come on.
Could this be the reason why hot starts are a problem or am I just dreaming?
I also occasionally get a code 54 which is a voltage to the fuel pump problem but could these two be related?
Many questions which I don't know the answers to!

Bob,

First, I fail to understand why you insist on always spelling your name backward.

Second, the grounded wire at the temperature sender on the right head would definitely cause constant fan operation.

Third, if the wire wms intentionally grounded, someone may have been trying to combat an overheating condition or the hard starting, but the grounded fan relay circuit itself shouldn't actually cause it. Repair the fan circuit first, since it should be relatively easy.

Excessive cranking after heat soak is most frequently caused by a rich condition on hot starts, possibly from injector leakdown. Does it help to hold the throttle at least halfway open when hot cranking? This could indicate a rich condition.

The next time you park it hot, try restarting after about four minutes. Turn the ignition on and wait a couple seconds before cranking. You should be able to hear the fuel pump rinning to create rail pressure. If it starts easily, wait about twenty minutes, then try again. If cranking is excessive, you may have some injector leakage. If you have a fuel pressure gauge, you can monitor the fuel rail pressure after shutdown. If the pressure bleeds off significantly after fifteen minutes, you have a leak somewhere.

First off Vader let me say that my name is not spelled backward, you're just reading it backward. HaHa.
Back to the problem at hand. You may or may not remember I've tried a few things over the last year to try and fix this problem.
The injectors have been serviced by Rich@ cruzinperformance. He said there were no leakers.
Even after servicing I still have leakdown after shutdown. Pressure drops to near 0 in about 30 min.
Sometimes when turning the key "on" I can hear the pump energize and sometimes it doesn't. This I assume is setting the code 54 but even if the pump does energize it still takes some excessive cranking.
Have you got all that? This problem is driving me crazy. What now?

If you don't always hear the pump, you might look at the fuel pump relays. Also, you may have a bad fuel pressure regulator if it won't hold pressure. ~Arnold
