One for the gurus please. If my car has been sitting overnight, it takes a fair bit of cranking to get it started in the morning. Same if it has been parked for a few hours. If it has only been off for an hour or two, no problem. I am thinking possibly fuel pressure dropped while it has been sitting? Have checked fuel lines for leaks but found none. Did notice that when the short vacuum hose was off at the drivers side of the balance pipe it did start easier. Any ideas gents? Tony
Possible leaking injector would be my guess. Symptoms as described. Service manual says to check in this order: Check battery / starter Check fuel pressure (pinch fuel feed hose whilst starting) Check injector for leakage (Press accelerator fully, if it starts easier check injectors for leakage) Does each injector make an perating sound Check ignition spark Check spark plugs Check EGR (if it sticks it can cause hard starting) Check ecu connector / powersupply Try known good ecu Check timing belt.
id check for boost leaks . and change your fuel filter..after that. your starter could be on the way out. does it make a spinning noise when u crank the car sometimes?
hi there, i suspect vacuum leak...buy some throttle body cleaner/carby cleaner and spray it around the vacuum hoses. if the engine rpm goes down when u spray it accross a vacuum hose- replace that hose. cheers marlon but becareful where u spray it (paint etc) as its very strong stuff
compression... also check the compression of your motor... an engine with low compression will be difficult to start when cold. Cheers
Basically rule of thumb is if its not spark then its fuel, if its not fuel then its timing. If you eliminate in that order you should find the problem. Doesn't matter how advanced any engine is, they all need these 3 to run. just more advanced/complicated (VG's lol) engines have more shit to look through in these 3 elements. Vac lines will be an issue for idling coz its unmetered air that the computer doesn't register and supply with the right amount of fuel, and can effect starting if there's a big enough unmetered air intake but in this case it shouldn't be vac lines. I've run mine with vac lines off and it started the same, just idled rough. How did you go with the vac lines?
