Firing order is 165432 , #1 on the distributor is pointing towards front of the engine and you go clockwise from there. #1 plug is driver side front and goes back 1,3,5 ... passenger side is 2,4,6 ..

Have you checked the fuel pressure?

I would check the fuel pressure regulator and if thats ok i would look at the fuel pump....First do you notice if the fuel pump is operational when you turn the key on??? It is supposse to turn on for 3-5 seconds then shut off...This feeds fuel to injectors for cold start... Try turning the key without starting motor and listen for the fuel pump operating as described above...If no sound is heard further diagnoses should be done ... Fuel pressure check and fuel filter replacment..

Pop the hood and locate the TV cable it has a button on the side... Push that button in and while holding down push the tip of the housing(for the cable) in.. this retracts it completely..Once retracted , manually open throttle to wide open position...You will notice that the TV cable will ratchet out .... This is the proper setting for cable.....Good Luck!!!

I would check the condition of the fuel pressure regulator. If it's ok, I'd say you probably have a bad computer.

The camshaft bearings should always be aligned so that the oil holes in the camshaft bearings are aligned with the oil passages in the engine block regardless of their position.

first make sure it doesent have 2 fuel pumps, one on the block and one in the tank , then look for a hole in the line , follow the lines all the way back to they turn into rubber, a mouse did that to my truck 1 small hole i found it after i replaced the pump , oh another thing if you replaced the pump at the block make sure the rod is in right or it wont ride on the cam , i did that before to . i put the rod in wrong and no fuel, and check and see if fuel comes out of the fuel filter on the left side under the drivers side door it might be clogged

honestly do not know but when i change them i use a universal sensor and i cut and join the wires with a block connector

You'll need to remove the starter, the inspection cover, remove the three bolts going thru the flywheel into the torque converter. Disconnect the driveshaft, support the transmission and remove the transmission mount and crossmember. Disconnect the downshift linkage, any electrical plugs, transmission cooling lines and the shifter linkage. Lower the transmission to get access to the 6 bellhousing bolts, becareful that you don't lower it too far, because of the distributor at the back of the engine. Remove the 6 bellhousing bolts and it should be ready to come out.

That year should have been either a 263ci 4.3L V6 for C - series trucks and the 350ci HO 5.7L V8 for K -series trucks.

What do you mean flashing? like rythmic flashing like the hazard lights of flickering like a bad connection? Both? at the same time? Tail lights and brake lights?

Is the speed sensor that you are using the original one, or is it from the Camaro, or is it new for an 89 K1500?

The worm gear inside of the transmission on the output shaft that drives the speed sensor gear is not damaged?

No matter what speed sensor is installed the speedometer still reads the same?

For 1989 Chevrolet Truck K1500 1/2ton P/U 4WD 4.3L TBI 6cyl the Oil Pressure Switch is located under hood, center, upper engine area, above transmission bellhousing flange, mounted in block.

Good luck (remember rated this post).

The inline will not work,it can not get fuel threw the fuel pump in the tank,the fuel tank has to be removed,and the fuel pump changed out.

You need to remove the steering wheel. Then remove the lock plate. Then unbolt the turn signal switch and move it out of the way. Remove the connector for the key dinger to access the bolt that holds the lock cylinder in.

Fuel filter is on the rail under the truck,the fuel pump is in the fuel tank.
