Asked by Jan 09, 2014 at 11:35 AM about the 1992 Pontiac Grand Prix

Question type: General

I have a 92 gp that i got from my aunt (family owned most of its life) and it wont start.
Shop (that i dont trust) said my internal drive chain (they said car has a timing belt and chain) broke so it wil only turn the head and not the lower half (pistons etc. quoted 1500 for repair when timing belt, not chain was done less than5k ago and ran good till it died on the highway) but heres where its wierd. The car has spark from wires to coil and i have fuel pressure, pump turns on, starter cranks, battery good, injectors spray (have intake off and smell gas from the chambers and will smoke gas from intake), all fuses good, etc and if it was the chain, if it has one, wouldnt my crankshaft and everything not move? cams and all pulleys move when i crank it over. Also the car has only 80000 miles so what parts could fail in that time? has to be a part that wears with no use and this cars wirings near perfect, no molesting was ever done to the car! only 200 made with the onboard HUD on the windshield and console computer with digital maintanence recorder and might i add ecu works flawlesssly so im stumped... it it really the chain? and shouldnt they have replaced the chain when the belt was done? fyi i only payed $100 for it so should i junk, part out, or pay $1500 to fix. It still looks like a BRAND NEW car

From what I found, your engine uses a timing belt. IT should be replaced around 80K. It's a 4.5hr labor job plus parts. If you only paid $100 for the car and it looks brand new, you might want to fix this car up if you like it. FInd another mechanic who you can trust to repair it properly.

Agree with Tom, it's worth fixing. But it may be something even simpler than a bad timing belt. If the distributor is turning (you're getting spark, you said) then the belt hasn't broken. But more than likely, the belt tensioner is worn out and that has allowed the belt to skip a tooth or two. In that case, the engine will act exactly as you described. A new tensioner is about $35, labor is the same as replacing the belt, which should be done even if it appears to be okay.
