ok well i had to replace 2 valves on my h23a1 and i put it all back together and bought a new main relay and now i can't get my fuel pump to turn on any thoughts???

 

Check all of your engine grounds , check your fuses , make sure that the fuel pump works

 

the main relay controls the fuel pump.

 

^ Yep.

 

When you turn the key to on, without starting the car...does the CEL come on for 2 seconds then shut off? During that two seconds can you hear that low buzz of the fuel pump priming?

If that CEL doesn't do that, and the fuel pump doesn't prime...make sure that small ground wire attached to your thermostat housing.

That is what fixed my similar problem.

 

That was it
it started right up thank god WHOOP WHOOP

 

ok now i have a new problem my number 2 cylinder will not fire i have spark and gas and when i pull the plug off it doesn't do anything help please

 

what do you mean it doesnt do anything?

 

like if i pull the plug from number 1 its starts freakin and then i do 2 and nothing 1 3 4 i pull the plug and still freaks 2 nothing again

 

pull the spark plug out of #2, ground it and see if it sparks when you turn the motor over. If it does, make sure you have the fuel injector plugged in securely.

 

i did that and i do have spark i've switched in jectors around ands still the same thing and only on cylinder 2

 

if the problem only occurs on #2, then you have a problem with either the connections, harness or computer, start by cleaning the pins on the connector, make sure it is fully plugged in and work from there.

 

Thanks bro as soon as this storm blows by i'll be out there it just doesn't make any since to me as why cuz everything worked before i had to take the head off

 

test the voltage to a body ground at the ecu injector pins. Use the back probing method.

Connector A, pins 1,2,3,5

they should all show battery voltage. I am going to assume that the #2 injector pin is going to show lower voltage than the rest. If it does, then your ecu is toasted and needs to be replaced.

 

hmm damn i'm srry to say this but thats not it
unless i didn't do it right i put ground to the car and red to the pins unless you ment put the ground back to the ecu

oh and the ignition needs to be on.

black to ground, red to pin

you said you have fuel, do you have fuel in #2 or not? pull the plug and see if you smell fuel.

if you have spark and fuel but no fire then you probably have a problem w/ compression. you did say you replaced valves right?

 

yeah i've pulled it switched it tested the injector plug for volts did what blake said with the ecu and still nothing and the valves were on cylinder 4

 

What valves did you replace? and was the car running before you started repairs? There are alot of things that could have been said that weren't imo. If you have fuel and fire to cyl 2 and nothing is happening then you have a compression problem imo. Check compression and make sure your spark plug is clean. I have heard cases of getting spark when grounded but none when reinstalled into the motor. Make sure you check compression.

 

spark plugs are new and i can hear the spark when i barly pull the boot from the plug and i'm getting compression and i replaced the intake valves on cylinder 4 and yes it was running fine before i did repairs (putting crower stage ones in and belt slipped)

 

Pull the spark plug out and check the spark that way. Listening isn't the best way imo. How do you know you have compression? have you done a compression test?

 

i did that and it sparks no i haven't done a compression check but i had the spark plug out and turned it over it had compression but i get what your saying

 

thought i could have been the connector clip cuz it looked bad compared to the others and still nothing
checked the pins on the ecu all good and nothing so i'm so pissed and lost so idk

 

checked the compression and its 60 and i don't thing its a bad cylinder i might have [freak]ed up the head gasket so hey we go again:-/
