Should have coil packs instead of distributor, check the power wires (one on each side of coil packs), if they are tight and getting power, the plate that the coil packs set on might be bad, take off and have tested at parts store.

R50 pathfinder vg33. Fires but will not start.


Hi Troy, You mention replacing the distributer? Have you set the ignition timing and have you made sure of the firing order, the position of number one cylinder and the rotation direction of the engine in relationship to the direction of rotation of the distributer. Does you vehicle use solid state ignition or points and condenser? Let us know more info and we'll be able to help. Regards John

My crank shaft is rotating twise the crank shaft. HOW MY 1342 FIRING WILL OCCURE?, I can spare only 30 digree for charge and spark plug contact. THERE ARE ONLY 2+2 CYLINDER. 180 DIGREE APPART KINDLY REPLY...


Your crankshaft turns 2x times the camshaft. Put it this way as # 1 cylinder reaches TDC (top dead center) of the firing/compression stroke, and this will be after a (8 degs BTDC) spark to ignite the air/fuel mix, the # 3 cyl. will be at BDC of the intake stroke and as #1 begins its power down stroke, (during explosion of air/fuel mix), #3 begins its compression up stroke, the #4 cyl. will be coming down with #1 cyl. but #4 will be in the beginning of its intake down stroke, and #2 cyl. will be coming up with #3 but #2will be in its BDC of the exhaust stroke. Which has just fired previously to #1. 1342134213421342 etc. Now the cam turns to open / close the valves; In the outline above, #1 cyl. valves will both be closed. #3 cyl. will have the intake starting to close at this point. #4 cyl. will just be starting to open its intake valve, and #2 will be starting to open its exhaust valve. Is all this clear as mud? So as the crank makes one full rotation (in a 4cyl. engine) only the firing of one cylinder has happened.and at every rotation one cyl. will fire. So #1 at TDC then one full rotation, #1 back at TDC, but this TDC is half of its 4 cycles, (1)Intake, (2)compression, (3)power, (4)exhaust. this 1234 refers to the 4 cycles of the rotation not firing order.
