Question about 1987 GMC G2500

1 Answer

My van won't start sometimes

I have a security system on my van that works sometimes and sometimes not but never gave me a problem with my starting until lately. I had to push a little button under my dash and then it would engage the engine starter and start. Now, it still does the same thing but the starter will turn and engine will not start. Where is the problem as it starts sometime and sometime not. It may start ten times in a row and then it will not start at all and run the battery completely down after about 15 crank overs.

I am not convinced that the problem is the security system. When you push the little button under the dash, do you have to hold the button down while you crank or is it a case of push and release. This tells me how the security system is activated. Get back with me on these questions

If it was mine I would disable the security system for a period of time and see if there are any instances
where the vehicle does not start.

you could have a bad alternator not keeping the system at the appropriate level of charge. Or check the battery, replace with other known battery that is good and see if this fixes the problem. Clean all battery terminals. Dead shorts in battery can really create problems and sometimes can load test good but on the low side. Try the battery swap first if you have access to one

Typically dealers are the only people who can work with the security systems on cars. If it is a factory security system, calling a dealer would be your best option. If it is aftermarket, call the company that installed it. If you have a mechanic you trust, you are free to ask them for advice, but typically mechanics will refer you to a dealer for security system issues.

Why won't my chevy van stay started ?


One thing to check into would be the antitheft system. Not knowing what year or type of vehicle makes it hard to help. But like i said, engine shut down in 5 seconds or less is a symptom of a bad antitheft security system. This link explains.

The van will start and run for about 2 seconds and quit i changed fuel pump,filter,distubitor,cam and crank sensors and module


Gm vehicles have been known to have faulty anti theft security systems. One of the symtoms of this is when your vehicle starts for 1-5 seconds and then stalls. A good way to know if this is the problem is when you see a light on the dash that says SECURITY. If you see this light flashing or on solid, this explains the van not starting.

The security system (VATS/PassKey) is having problems, it's typical on those cars. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

Security light on dash lit


i have this same problem. it has to do with the passlock security system that is factory installed. my system is cold weather sensitive. you go to start it and it will die. the security system then goes into stupid mode and its a 10 minute wait so the computer wont think your stealing your van ,then it will restart. sometimes it goes into another ten minutes if you try starting it to soon. security light flashing equals no start. solid security light equals ok to start. the system cuts power to the fuel pump. i live with it. it is managable but frusterating.
