  • 1999 GMC SIERRA
5.4L V8 98K Mi. We have fuel pressure, and spark. But this truck has always intermittently sported a 'Security' light on the message center. Didnt seem to effect anything.
But last time this happened, we used a different key - and the problem went away (still had intermittent security lights tho).
Right now it just acts like it starts, but then sounds fuel starved and dies.
I used to like this truck.
Do you
have the same problem?

I would start by checking for codes, in the event that it is an anti-theft mal-function.

IS the fuel pressure in specification, as it is critical; not just present?

Thanks for your reply.

Yes 60psi.

Also, after beating on it for about 30 minutes, I walked away - and an observer said the alarm turned on for about a minute then shut off. I dont think I had the fob in my pocket - and that is the only time it has done that that I know of.
Also, this does not use a chip key.

It's going to be a time bomb waiting to not start at a later date if you don't address it I would think.
