Do a compression test. The pistons and rings may not seal enough anymore. Try push-starting it in 2nd gear. When you push it ,it will turn the engine faster and build up more compression, enabling combustion to take place. Aslso check if the fuel pressure regulator is not leaking through the vacuum hose, causing it to flood.

starting with your left front its 1-3-5-7, 2-4-6-8 standing in front of truck the left front cyl is number 1, on the pasenger side of engine. remember leftside is 1-3-5-7 rightside is 2-4-6-8 an your distriberter cap has a 1 on it then just go clockwise with the numbers

firing order is 18436572 drivers bank 1 3 5 7, passenger 2 4 6 8

Most all Chev or GMC v8 engines use the firing order of 1-8-4-3-6-5-7-2. You have to find where #1 is on the distributor cap which is usually closest to #1 cylinder then looking toward the back of the engine go clock-wise to install the rest. Don't get too close to the headers. Plastic melts!

If you are talking about a 350 Chevrolet (GM) engine, the #1 plug is at the drivers side front. To find the position on the cap, turn the engine 'till the timing mark on the lower pulley points to 0 on the scale, then check rotor position in the distributor. If it's pointing towards the firewall, make one more turn. The firing order goes in the direction the rotor turns when cranking the engine over. 18436572.

350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.

that has a votec engine in it the fuel pressure is droping at knight and it takes 60 psi before the injectors will fire most likely cause fuel pump ,leaking injector ,or a feul pressure regulator

does your starter turn the engine at all?

the firing order is
1-6-5-4-3-2
