Having problems with your 1994 Chevrolet S-10 Blazer ?
1994 chevy blazer
new spark plugs
new fuel injector (spider gear central port injector)
new map sensor
new oil pressure/fuel cut of switch
all this and it still wont start,
it turns over and tries to start but it wont ? any ideas?
next step is grounds and fuseable links,
there is fuel at the rail and the fuel pump primes
So you have fuel to the fuel rail. Do you have spark to the plugs? Pull #1 spark plug boot and see if it will arc about one quarter of an inch to the exhaust manifold bolt or stud.If no spark or a weak one is present then replace the coil. If yes then all we half to do is bring the two of them together ( meaning spark and fuel ) at the same time. disconnect battery and bring #1 cylinder up to TDC on the damper pully timing marks on the compression stroke.Once this is established remove the distributor cap and observe which tower on the cap the rotter is pointing at. It should be pointing at #1 tower.If not remove distributor and reinstall to #1 tower. Tighten distributor bolt to just to a snug fit to allow you to be able to rotate the distributor in eigther direction. Then turn the body of the distributor ( counter clockwise ) just so it is about a hair before #1 tower then stop.Now turn the rotter by hand ( clockwise ) to see if it will move in that direction all the way past #1 tower ,then release it to go back to its propper position. then all is well and the motor should fire right up. Finish up with timing light.And then tighten the distributor bolt down some more.I hope you find this helpfull.If you do then please give me a good rating. If you do not find this helpfull then give me a good rating anyway. Ha Ha Have a good XMASS.
