Question type: Maintenance & Repair

Put gas in using funnel
stirred up a bunch of
crap when I started the
blazer it died in about 50
ft. Just had Spider
replaced. I drained all
the gas trip placed plugs
wires fuel filter. But
injector cleaner high
octane gas it wants to
start but when I give it
gas dies. It sounds like a
air compression
problem but I don't think
it's getting gas. It's
blowing smoke

Check fuel pressure at the rail. If no pressure, check filter and pump. If pressure is ok, spray some quick start in the throttle body and see if starts for a bit. If it does, check crankshaft position sensor. If still doesn't run when u spray quick start, check for spark at the spark plugs. If spark is ok, check timing. If timing is on, do a compression test.
