Try doing a cylinder balance test take one plug wire off the coil at a time while running the engine to locate the cylinder thats not firing . then check the plugwires with dmv meter should be 7000 ohms per foot also engine running u can disconnect one ijector at a time to see if it makes a difference too locate the problem the engine wont change if the injector is not flowing fuel if feel it pulsate its working electricly may be still plugged.

Firing order for rocam1.6

A six cylinder in-line engine has a power impulse every 720 degrees/6 i.e. 120 degrees of crankshaft rotation. The crankshaft has six crank-throws placed at 120 degrees out of phase with one another, which can be arranged only in three planes. Therefore, the crankpin phasing is arranged in pairs. For heavy-duty diesel engines, seven journals and bearings are provided, at each end and between adjacent crankpins. For petrol engines only 4 or 5 main journals are provided. The firing order with the crankshaft arrangement shown in the attached figure is considered. With piston 1 at the top of the compression stroke, its opposite piston 6 is at the top of its exhaust stroke. Rotation of crankshaft through 120 degrees brings pistons 2 and 5 to their TDC and either one of these can be arrangement to complete a compression stroke. If piston 5 is arranged to be at the end of compression and at the start of its power stroke, then piston 2 must be on its exhaust stroke. Rotation of crankshaft through second 120 degrees positions pistons 3 and 4 at the TDC, so either one of these can be on the compression stroke. If piston 3 is made to be on compression, piston 4 must be on its exhaust stroke. A third rotation of 120 degrees brings pistons 1 and 6 back again to TDC, where piston 6 is arranged to be on the compression and piston 1, therefore, be on its exhaust stroke. A fourth 120 degrees rotation brings pistons 2 and 5 to their TDC. Piston 2 is now on its compression and piston 5 on its exhaust stroke. Rotation of crankshaft through fifth 120 degrees brings piston 3 and 4 to TDC. Piston 4 is on compression and piston 3 on its exhaust stroke. Final rotation of 120 degrees completes the 720 degrees displacement of crankshaft and brings the pistons into positions for the next cycle. This cycle provides a firing order of 1, 5, 3, 6, 2, 4. If the phasing of paired crank-throws 3 and 4 and 2 and 5 are interchanged, then a second equally suitable firing-order of 1, 4, 2, 6, 3, 5 is achieved. This arrangement provides excellent dynamic balance and evenness of torque, and is preferred for engines larger than 2.5 liters provided length is not a prime consideration.

Firing order and does it comply with the numbers on the distributor cap

not necessarily-- it complies with the position of the rotor button and the lead it points to in the firing order
so start with the rotor button facing no one piston lead with the piston on tdc compression
put the lead to no one plug
move the crank in the direction of rotation and when the rotor button points to another lead that is the next plug to connect to
so with a firing order of 153624 (example) the lead wil be on the point when no one piston is on tdc compression
the next point will be no 5 piston ,the next point will be no 3 plug and so on
work shop manuals are a good source of accurate information

Need to adjust the valves on a 3.1 oldsmobile ciera.There is no mark on harmonic balancer.

there does not need to be marks on a harmonic balancer to adjust valves
when a piston is on tdc the valves will be either completely closed or in the valve rock position
when adjusting valve clearence you will need to know the firing order because when no 1 piston is ready to fire , then the next piston to fire will be in the valve rock position
for example if no1 piston of a 6 cylinder ( firing order 153642) is at tdc firing both valves will be closed and so the valves of no5 piston will be rocking so that will be the nect piston valves to adjust and after that no3 piston valves will rock so you do no 5 valves and so on
a workshop manual will explain it all to you
