blonka Posted August 29, 2007 Posted August 29, 2007 hey this is my 1st project car so still abit unshure about things... whats hapening is when i turn the key it fires a few times but wont keep firing when i stop cranking it. does the car need to be running to do a compression test? does the fuel pump need 2 be on wen its cranking? what things could i chek to see whats wrong? any help would be great thanx Quote
peteretep Posted August 29, 2007 Posted August 29, 2007 could be heaps of things, the fuel pump has to be on for the car to run for starters though any more info on the car/motor? Quote
Toucan Posted August 29, 2007 Posted August 29, 2007 Yea mate bit more info. Is it carbed or injected? What car is it in? Standard computer? My 4age will run for 5 seconds or so after the fuel pump turns off before it dies. Checking spark, timing and fuel is the best thing you can do for a start. Quote
peteretep Posted August 29, 2007 Posted August 29, 2007 yeah, basically need to make sure fuel is flowing at the right flow/pressure. Make sure theres spark at around the right timing/is there spark on all cylinders/is it enough spark. If it isnt any of that stuff then it could be an array of things Quote
Mike-e Posted August 29, 2007 Posted August 29, 2007 whats hapening is when i turn the key it fires a few times but wont keep firing when i stop cranking it. check the power feed from the igniton switch "ON" to the power loom in your engine, also check "STA" circuit does the car need to be running to do a compression test? yes does the fuel pump need 2 be on wen its cranking? yes what things could i check to see whats wrong? Check engine input and output ancillary power feeds at on and start signals. Your constant feeds are white, your start feeds are black with white feature. yell out if you need further help Quote

CXGPWR Posted August 31, 2007 Posted August 31, 2007 Check Air flow meter & connection, and make sure the meter is earthed(if it has one) if not, check all things above. Quote

blonka Posted August 31, 2007 Author Posted August 31, 2007 i have had it running once, then found water leaking in the oil and a pistion so re-torqued the head to the corect settings, then tried 2 start a couple days later and no luck Quote
Toucan Posted September 1, 2007 Posted September 1, 2007 Have a check of all the engine wiring. I've just had to go over my bluetop loom as it was giving me trouble. I checked each wire for continuity and made sure all the connections were soldiered and good Quote
