when you pull the plugs and crank the motor, does it spark? probably a silly question for someone who chaneged his own t belt. :wink:

if its been stood without running for 15 years, im surprised it rus at all, leaded and unleaded fuel rots after a few years left stagnant, its possible the spray nozzles on the injectors are corroded or gummed up. try taking the injectors out, suspending them each in a plastic bottle, and crank over, see if you get a spray pattern.

take all six out at once but keep them attached to the fuel rail(have to remove intake)...each comes out with two small bolts removed(plug intake holes so you don't drop aNYTHING IN THEM)...also check fuel pressure


Also check that spark leads are in correct order...spark and timing go hand in hand


also ..check compression


also...double check cam timing and timing belt tension
