There is a small mark on the cam pully that must point strait down to the mark on the crank shaft timing pully. the mark on the crank pully is a bit hard to see but it is a low spot on the inside area. also lines up with the keyway grove in the pully.

What is the fuel pump pressure for a 1990 geo storm 2+2


storm what engine? 4xe1 or 4xf1 SOHC or DOHC (twin cam)?
its really an Isuzu Impulse in snack skins (badges)
does test fuel run engine? that is step 2.
if the cam timing belt slips, the DOHC goes boom.
the SOHC engine belt slip,cause no starts, due to huge
compression drop, and fails the test fuel tests.

SOHC, keyon, 30-46PSI
same for both. engines
but as all mPI engines it drop running at idle.
and rises at WOT> (FPR actions most work right running) ask
but its no running
ever do a 60,000 interval tuneup with a new cam belt.
no?

1990 geo storm sohc is running rough. Parts that are new: cap, rotor, plugs wires,plugs, pickup coil, and the ignition module looks brand new. The coil is old, but is still sending spark through all t


the timing is 180 degrees out so ignore where no 1 lead should be and rewire the HT leads to the new position for no1 cylinder. The crank timing mark should be on 10 degrees advanced. Engines are timed off the crank position so forget the cam position.
Or you can start again. Remove no 1 plug and turn the engine over until you feel compression under your finger over the plug hole. Set the timing on the crank to 10 degrees before tdc. Position the distributor so that the point of the star is directly opposite the exciter coil in the distributor. The rotor button should now be facing no 1 cylinder plug lead adjust the HT leads so that they will fire in the 1342 firing order. Start the engine and with a timing light attached to no 1 plug lead adjust the timing mark to specifications by turning the body of the distributor.

Firing order 91 geo storm


Firing order - 1 - 3 - 4 - 2

Cylinder # 1 is to the left when viewing the engine from the front of the car. They are, left to right, 1 - 2 - 3 - 4.

Looking from the side of the distributor... starting from the top right counter clockwise it's 1 - 3 - 4 - 2

Distributor timing


You need a timing light. You hook it to the no.1 cylinder and it flashes when that cylinder sparks. Aim the light at the crank. There is a timing mark on the crank and on the motor. You turn the distributor till the marks line up.
