S10 CAME IN MULIPLE CODES

the coil does not crank the engine , the starter does that, sorry.
(if you ever had to hand or foot crank and engine , youd under stand that. (like motor cycles or boat engines, or per 30s cars.)

in fact will crank all day with no spark parts on car..

x2, the scan tool does tell you why there is NO STARTS, CRANKS OK. The pcm can detect, one missfire in 10 cmp;ckp signals.

• CRANK FOR 5 SECONDS
• release, key
• scan tool has DTC errors?, read the believe them.

no engine stated of 4 or more,

U checked everything but spark,
why, check spark at all cylinders, all most fire or the engine will not run or stall.
That test be first, if not starting (AFTER SCAN TEST)

IF NO spark fuses are next , not last.
lets do no start fails tests. (cranks perfectly 200 to 300 rpm)

1. : check fuses
2. key on, CEL lamp must glow, if not , ECU fuse blown.
3. crank with scan tool , see P03xx DTC errors, see RPM dead.?
4. check for spark? got spark x4 or times number of cylinders?
5. got spark try test fuel now, runs for 3 seconds?
6. yes, runs on test fuel now means lost fueling
7. no, dont run on test fuel, means, 1 to 5 done wrong above or engine compression bad.
8. bad fueling, huge number of tests. check fuel pressure now.

confused, try a shop and watch them, learn.

have you tried holding the gas pedal down a little to see if it starts that way,if it starts then your throttle body/ IAC is dirty,if that didnt work, check for fuel pressure if you dont have a pressure guage you can un-clip the fuel line at the eng have a small plastic jug to catch the gas and have someone just turn the key to run ( not cranking it over) and see if a shot of fuel comes out of the fuel line,then have them crank it over and see how much gas comes out-if nothing or very little then you may have a plugged fuel filter or bad pump,or a bad fuel pump relay-if gas comes out,then it could be cam sensor or a crank sensor problem,assuming every thing else is good-you didnt say if the coil pack was new or used,or if you checked for spark,but a scan tool would give you a code for either the cam or the crank sensor or any other relavent code.A bad PCM will also stop the spark and the fuel,I hope this is helpfull

check fuel pump

You have three choices. First, check the spark and coil system to ensure you are getting a spark. Pull off a plug wire from the coil pack and crank. Have someone watch to see sparks snapping off the coil pack. If you don't have any replace the control module under the coil packs.

Second, you may not be getting enough fuel pressure. Put a gauge on the fuel pressure test port. You may have a bad oil pressure sensor, located down above the oil filter. Check that oil pressure sender and make sure the connector is pushed in. The power to the fuel pump runs through the oil sender. If the engine starts and oil pressure doesn't come up quickly, the computer will shut off the fuel pump. Check this and you can also manually engage the fuel pump from the relay block down by the passenger feet.

Third choice, and it's a long shot, check the harmonic balancer and the crank position sensor. If the sensor is bad, the computer has no idea when to fire the spark plugs. A magnet is on the harmonic balancer and flys by a sensor to induce a voltage in the coil and tell the computer what position the crank is in.

You also may have a bad computer.

You can figure it out.

the icm, coil, and crank sensor all read off the opti. Chances are you have a bad optispark (distributor). I just went thru the same issue and found it to be the problem.

check your fuel pressure as well, you may have anissue with your fuel pump and or relay

It sounds like fuel starved at higher speeds. i would change the fuel filter first if this does'nt help check the fuel pressure

check intake for vaccum leaks,the gasket also and egr valve, thats alot of parts to have replaced without diagnosing first, if there are no fuel leaks and you said all injectors were replaced then you have a defective fuel pump, also these engines had misfire problem because of dirty injector but you replaced them so count that out. good luck.

Hi! You must be frustrated by now! your code is marking that the O2 sensor is bad in bank 1. Did you replace the O2 sensor that is located  before the catalytic converter?  The S10 has an O2 sensor specially made for that cat. its about 30$ That would explain for your blackened spark plugs; your pc on the car is asking for more fuel. GOOD LUCK!!

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

ty unplugging your MAP sensor then starting it, if that don't work plug the MAP sensor back in and try to start it. another thing to check is your cam sensor as your crank and cam sensors have to work in time with each other.
