'87 Chevy ramdomly DIES.
I picked up a 1987 SWB 4x4 for my son. The truck is really nice and seems to run really strong. However it occasionally dies while driving. After a couple of minutes it will start right up. Its rather complicated to trouble shoot when the problem fixes itself. Have any of you out there experienced this problem?

Re: '87 Chevy ramdomly DIES.
TBI with ESC/EST I guess. The electrical system remains functional?
A clean stall and easy restart without touching anything (occurring at random times, unrelated to engine temperature, load, weather conditions, etc.) would generally suggest an intermittent electrical issue. I would start by looking at the wiring to the distributor. To determine whether the problem is fuel or ignition related, keep a can of ether handy. Next time it stalls, get out and spray a healthy shot of ether into the air cleaner. This has to be done quickly while it is still in a no-start condition. If the engine fires up on ether but then quickly dies, look at the fuel pump circuit. If ether doesn't get it to start the problem isn't fuel related and you should concentrate on the ignition system. |

Re: '87 Chevy ramdomly DIES.
if its the ignition system with these systems its usually the module in the distributor or the HEI coil but id do the tests with the ether first

Re: '87 Chevy ramdomly DIES.
I experienced the same thing with a 87 I owned. Ended up being wiring at the fuse box under the hood
Get it to run and the while its running try wiggling wires near the fuse box. Worth a try anyway

Re: '87 Chevy ramdomly DIES.
I'd look at the coil and distributor.
When I first bought my 89', the owner said "sometimes, it just doesn't start". If I waited a while, it would just fix itself. Finally brought it to the dealer and found a bad distributor. Just an idea. Or perhaps the fuel pump.

Re: '87 Chevy ramdomly DIES.
My 88 Blazer died and would not start back up even after waiting a few minutes or the next day. I sprayed ether and still no start. It was the ignition module in the distributor. I think the random problem could be the coil, but I would do the ether test first to eliminate a fuel delivery issue.

Re: '87 Chevy ramdomly DIES.
Thanks for all the advice. I am ordering a good iginition control module and installing it. Since the problem is so quick to fix itself I haven't been able to try starting fluid.
