I have a 96 chevy s10 blazer, it's got good fuel pressure, good spark,checked sensors. why wont it start?

Answer 1

coil wire is known to burn out,check coil wire

Answer 2

We could all guess, a lot, I suppose, but the information yo have is a bit skimpy.
Got a better idea -- DIAGNOSTICS!
The little Blazette is OBD II compliant, so the no-start condition may well have set a diagnostic code. to find out, you will need a code reader (some discount parts stores have them for as little as $35.00). When you connect to the DLC beneath the dash, it will retrieve the DTCs. if it doesn't offer descriptions, go here------>

http://www.obd-codes.com/trouble_codes/index.php

...and locate the description, and this will identify the circuit or system that is at fault.
Refer to a repair manual for proper diagnostics. Don't assume that if the code P0335 indicates a failed Crank Sensor. It may indeed have failed, but a loose or corroded connector on the sensor will set the same code. Follow the trouble tree for diagnostics, then repair the fault. Save time, money, effort and frustration. When you have repaired the failure and it runs, THEN clear the code. AFTER the repair.

Good Luck

Answer 3

I would suggest that you take it to a mechanic and have him check the pickup in the distrubutor,these are bad to go out, what this does it provides a signal to the injector (throttle body injection) for the fuel pulse,this can be checked with a noid light.

Answer 4

you could desire to purpose unhooking the battery for approximately 2 minutes to allow the laptop to "relearn" Your truck could desire to start. If no longer then it sounds prefer to me that in case you're transforming into 40 8 psi, then sure it is going to likely be a issue with the injectors. Did you get any airborne dirt and airborne dirt and mud in the gasoline line ? if so the injectors themselves could be plugged. If no longer then, the injectors probably are no longer pulsing. [ no longer recieving sign to fireplace] Take a attempt mild and probe [do no longer decrease] the injector terminals, between the wires ought to fireplace on each and each injector jointly as the engine is cranking.

Answer 5

remove the top plastic intake manifold.pull all the plastic fuel injectors out and crank the engine over. make sure gas squirt out all the injectors.if not,replace with a new improve injectors kit(cost about 350.00).DEALERS part only

Answer 6

How good a fuel pressure? I believe it must have a minimum of 50psi before the computer will let it fire.

Answer 7

have you checked the timing on it,,it may have jumped timing,,i own a repair shop,and i get a lot of them that have jumped timing,and it wont ever start if it has you,ll need to check it to see if it has,and if so it will need a new gear and chain set i it,,good,luck,i hope this help,s.

Answer 8

did you check the plugs,to see if they are firing good.maybe they are fowled and cant fire.
