PROBLEM:
740 GLE Won't Start When Hot - Wait 1/2 Hour Okay. I'm having this problem with my '90 740 Wagon. Very frustrating - have replaced fuel pump relay, fuel pump, fly-wheel sensor... all to no avail. No error codes from computer are showing up. Any ideas please?????????
SOLUTION: I have found the problem - hurray! I found the fix on the UK Volvo Club site - the problem was the noise suppression relay, which also supplies
- power to the fuel injectors. There are two identical relays side by side - the noise suppression and the auxiliary fan relays. After reading the following diagnosis for the ns relay, I switched them and the car started right away. Switched them back and no start. Back again and started again right away! Problem diagnosis: When this relay fails, it can cause: · Hot start problems (car won't restart until it cools down) · Failure of fuel injector system (no injector pulses) · Backfiring or balky acceleration (insufficient or inconsistent injector pulses)

but I've got the LPG Gas also,..in the LPG the symoptom is the same,..but when LPG is turn on, the injectors, fuel pump, or all the fuel system is turn off,...this sympot is in the Ptarol NoPB ant in teh LPG Gas. But, I've written that I can starts the enegin when it's hot, but I must used a strter long time (whent is cold, it starts imadietly, when is hot, I must used strter 5 seconds). When it'c cold and starts good, the car go better (the power and acceleratio is better), that wehn is hot and starts with problem.
