okay he is the deal.
so last friday i was diving to colten to my buddys house to get is 89sas toy ready to go night wheeling and its a hour drive from my house and it ran fine all the way there. after i got there we got his truck ready and warmed up then i went to start my truck and and it fired then died. then it wouldnt stat. i checked spark and it was good but it didnt have fuel going to the motor so it was the fuel pump. i pulled out the gas tank and found the ground on the fuel pump ground came loose. so i fixed that and it started right up and idealed fine. then i put it in gear and it was running weak as he**. so i drove it home and it had no power at all. barly got it home. then i did a commpression check on it and its 175 in each cylinder. then i pulled the valve cover to check for a flat lobe on the cam and i stock valve but they were fine. then i took it to a shop and they diganosed it and said the injectors were not getting pulse so then i check the wireing harness and two wires were grounded out. i fixed that and its still running on 3 1/5 cylinders nothing to #3 and barly anything on #2. so i dont know what it could be... good compression good spark and gas cause the plugs are soaked in gas on the 3rd and 2ed cylinder. so what else could this be? im lost please help

check your injectors and make sure they are spraying in almost a pyramid shape like this /\ out of the injector you may have a clogged injector and you can either have them cleaned and gone through or you can just buy new ones but just have them cleaned is cheaper

the shop ran a test on them and they are spraying good. idk what else it could be man lol

vaccuum leak....

Halladay · « **Reply #4 on:** Jun 03, 2009, 11:45:54 PM »

thats what ppl have told me too but i didnt know if that would cause it to not run on cylinders

toyotanner · « **Reply #5 on:** Jun 03, 2009, 11:50:13 PM »

well if it has good compression on all 4, gas on all 4, and spark on all 4 to all cylinders how could it be running on 3.5 cylinders? maybe its something stupid like spark plug gap... anyone else have any ideas?

Halladay · « **Reply #6 on:** Jun 03, 2009, 11:54:12 PM »

ya what else do you guys think? i know it has gas cause the plugs are soaked and the plugs are sparking likes its the 4th and great commpression with working valves. im stumped and the shop dont know! what a shop huh? lol (wrenchs auto repair)

could just be off on the timming

jimbo74 · « **Reply #12 on:** Jun 04, 2009, 11:07:50 AM »

are plugs properly gapped?

pre-gapped plugs, are seldom really gapped correctly......

Halladay · « **Reply #13 on:** Jun 04, 2009, 11:37:10 AM »

im about to check that... the timing is dead on with the mark on the timing chain cover and the crank pully so timming is good. what are plugs suppose to be gapped at on a 22re?

i think its .044 but check the emissions sticker under the hood, it says on there

the cam should have the little tag @ 11 o clock when the dizzy rotor is pointed to #1 on the cap, and the #1 cyl is at tdc, with the crank @ 0*

i think its 5* of timing for the 22re with a jumper in the diagnostic port

Gap is .031"

Halladay · « **Reply #17 on:** Jun 04, 2009, 11:37:11 PM »

ok the gap was fine... i sparyed starting fluid are around the intake too to check for a intake leak and found nothing.... i dont get it lol

Tallchevy · « **Reply #18 on:** Jun 05, 2009, 12:05:49 AM »

You might have a loose or broke wire in the engine harness. Start the engine & grab the engine wire harness & start to move it around to see if it clears up. The ground wires for the injectors in my harness broke where the harness support bolts to the intake.

Halladay · « **Reply #19 on:** Jun 05, 2009, 12:10:43 AM »

lol thats funny you said that cause my did the same thing and i fixed them and its still running like a dog terd

Tallchevy · « **Reply #20 on:** Jun 05, 2009, 02:21:46 AM »

I would recheck the harness anyway.

Halladay · « **Reply #21 on:** Jun 05, 2009, 08:57:45 AM »

okay ill go through it today.... keep you posted

Halladay · « **Reply #22 on:** Jun 07, 2009, 10:55:21 AM »

problem fixed! i was thinking intake leak so i ripped off the intake and found out the the gaskit that is on the intake and head got destroyed and one of the water ports was getting water into the intake. then i was in it so i replaced my injectors with some high flow injectors and it is alot faster. im pushing 35's stock gears up hills 4th gear at 50mph lol

kneedownnate · « **Reply #23 on:** Jun 07, 2009, 10:37:56 PM »

Where'd you get the injectors, and can you provide specs?

Halladay · « **Reply #24 on:** Jun 07, 2009, 10:49:23 PM »

i got them through baxters auto parts they made a huge difference. they are Bosch Green Top 465cc/min injectors. i paid 360 for them and they are worth every penny! this is a link to a web site with the sme injectors i have. http://www.fiveomotorsport.com/Injector_MILLED.asp they are the second one down (lime green and black)

Are you running a turbo engine? It says that these are for "forced air induction".
