    also u need to know what the fuel pressure is, just because u have some flow doesn't mean the pump is working right, it should have at least 40PSI during cranking, u will need to buy a fuel pressure test guage from an auto parts store, about $20

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!

My 200 blazer sits all week and this past saturday


Seems as though your mechanic needs to check for some chewed wires but a bad cap and rotor as well as plugs and wires have been known to cause no starts on these trucks for years.

Sounds like water/debris in the gas tank. Try adding dry gas to the tank. Changing the fuel filter also a good idea.

o2 sensor will not stall your truck,ecm will bypass o2 code and run on open loop,or ecm default setting,dont search further ! your problem is all related to remote starter and bypass,youll have to fix wiring properly to original state,or your problem will probably get worse!

Wont start up...


Check for a bad ground from battery to engine. Then check the module inside of the distributor cap. It should be a black crescent shaped unit about three inches long that all the wires plug into.
