Gtr Wont Start?

[Rude Carz]

hey guys,

i have had my gtr sitting for about a year and went to start her yesterday and she doesnt want to kick over??

anyways i checked everything out and 4 out of 6 of the coil packs were sitting in water (down where the plug is), looks like it has been sitting there a while too. so i got all the cr@p out and fixed that up.

also, the fuel has turned to varnish.. i took the filter out on the pump side to find out if i have any pressure. i turned the key and some fuel came out but not that much and then after about 4 seconds it started dripping like it was clogged? i turned it off and then back on and there was nothing still? waited 30seconds and redid it and pressure and then it died again!

im wondering if the pump is dead, causing it not to crank over? or could it be the spark plugs.. new iridums.

That's a long as time to be leaving a car sitting.

Sorry I can't help you out though mate. Goodluck with it. Hope the engine didn't die.

[Rude Carz]

ok, i just cleaned the lines that go prety much up to the reg..

i have checked the packs for spark.. all clear..

i have checked the packs with plugs on the end.. all clear..

so, its got fresh 98octane in it.. clean lines, tank, and pump.

what the hell else is there?

help!

[Rude Carz]

just checked the fuzes that are needed for it to start, all clear...

really running outta problems???

ok, injectors were fully flow tested and cleaned today, they were fully blocked..

still.. she is not cranking over, put some aerostart in the vac lines and she wanted to start but couldnt..

i am begining to think its the CAS. it might be stuffed or seomthing??? i dont believe i am getting any power to the injectors.

either that or the ECU is stuffed!

i need some advice here!!!!!!!!!

It may have fouled plugs, pull one out and see if there wet with fuel.

[Rude Carz]

dry as a bone.. dry dry dryyyyy

i dont understand :'(

[aphid]

so i take it you're sure the injectors are firing properly now? maybe pull them out and take the cas off and give it a spin too verify that they are properly working..

after having the coil packs sitting in water for so long perhaps the springs that sit inbetween the bottom of the coil pack and the spark plug have become corroded, try checking them out

[moshr32]

You need to get a hold of a noid light to see if u are getting an injector pulse.

If no pulse could be crank angle sensor but most likely faulty ecu.

[Rude Carz]

the springs are fine, they wernt touched by water,

how do u check if the ecu is buggerd??

dan

[moshr32]

U need to check if your injectors are getting a pulse from the ecu.

[Rude Carz]

so, that is something to check at the ecu? does someone have a pin out diagram of the ecu so i can check if they are getting power? what amount of volts is 'enough'?

its a stock ecu by the way

dan

[moshr32]

U need to remove an injector plug from the top of one of the injectors and insert a noid light in the plug.

If u are getting a signal from the ecu the light will flash,meaning if u have spark like u say its not likely

the ecu. Next step would be to check compression.

U may be able to purchase a noid light from repco etc or borrow one from your mechanic.

Good luck

[Rude Carz]

yeah i got compression

ill get onto that noid light

i put a multi onto the plug and cranked it and i had .5 volts... so i am assuming the CAS or ECU is buggerd

[moshr32]

Fuel pump working for sure?

[Rude Carz]

yeah i got a pressure gauge on to it and she is showing lots and lots of pressure

[Rude Carz]

will a rb25 ecu work in a 26 as a test? my mates got a 25 ecu!

thanks guys

dan

[Rude Carz]

??? anyone ???

[Rude Carz]

ok, just ran ecu diagnostic and got a 55 back.. so all is good there.. i dont understand???

i shot some aerostart in the vac line and it wants to crank over and splutters a bit and waht not..

i have pulled out the CAS and it is fine although i havent put the ign on a turned the sensor to see if there is injector pulse..

HELP

does anyone live in brisbane and would be able to help me out?? PLEASE!

Mate trhis may sound silly but have you changed the fuel filter since you said it was blocked? If you really wana know, pull out your injectors, crank the car & see if they spray fuel. Maybe even one will do... Do the same with your plugs if you havent already
