Hi Everybody,

I have a '91 Suburban with a 350. I was getting a service engine light that was pointing to the EGR valve. On Thursday I replaced the EGR valve and it ran great. Drove it all day Sunday without any problem. Got home Sunday night and parked it. Went to start it today and it won't start. Just cranks. I'm getting a code 32 which points to the EGR system again. Any thoughts on what in the EGR system would cause it not to start?

Thanks

 

Is it operated by a solinoid? maybe thats passing some vacuum and keeping the valve slightly open at idle,it should be closed at idle and open regulate above idle

I ended up towing to the shop. They said it was some coil in the distributor that went out. The distributor shaft was loose too so they ended up just putting in a new one. Runs great now.

 

The distributor shaft was loose?????????????????????????????????????? GTFOH The coil may have went bad and the distributor was more expensive to replace than the ignition coil module.
