Mr Fix

Car was running and randomly died and had not started since.

I have no spark no fuel no injection pulse.

At the main relay I do not have power going to the fuel pump black/ yellow wire but the relay clicks and I have power as shown in the picture. The blue and red wire which is labeled for st switch has no power and when I tried to jump power to it, it melted my jump wires so I am getting ground there on terminal 4.

When I jump 12v to the black and yellow wire the fuel pump comes on and I get fuel but still no spark.

The ignition coil is good based on resistance readings and I put on a brand new dizzy before I knew I had no fuel. So with new dizzy still no spark and even with fuel pump jumped at relay no spark.

What else do I need to check, what's next? Ignition switch? How do I test that.

I have no trouble codes or cel, the cel stays solid with the blue connector jumped, so there are no codes to read.

There is no alarm and it's not a coded key.

See picture, red circles mean 12v present with key on, and black circles are ground.

I tested the ignition switch and I have igi and igi2 and acc power everything looks good with the ignition switch. What else can I check

There are several fuses involved. Also the ECU ground wires are on the thermostat and if they lose ground the whole system quits.

If it's a 92 to 95, resolder the main relay.

When you turn key on and don't start the CEL should go on and back off, at the same time the main relay clicks and the fuel pump runs then stops. Under the hood with the key on you should have 12 volts on the yellow-black wires to each injector, and on the black-yellow wire that feeds the distributor.

Mr Fix

I have power at injectors and distro and coil just no pulse or fire signal also no fuel. I checked all the fuses the ignition switch is working right I tested all the poles and its good.

If I jump power to fuel pump at main relay I get fuel but no spark.

But the CEL does cycle and the fuel pump primes when you turn key on but don't crank?

Pull the brake handle up and make sure the brake warning light stays on while cranking. It is on the same circuit as the ignition system.

If the electrical stuff checks out OK next you would move to checking mechanical issues such as a bad timing belt. If the cam / distributor does not rotate there will be no fuel or spark. This can be checked by taking the oil cap off and looking for the rocker arms to move. Also you should take the cap off and TDC the crank and confirm the rotor points at wire #1 (or #4, you would need to turn the crank around once to get it to 1) Do not crank the engine with the distributor cap off unless you unplug the low voltage wires or hold a grounded test wire near the coil output. Firing the coil into an open circuit is prone to damage it.

If distributor is turning, crank the engine continuously for 15 seconds then check for codes. Distributor sensor codes would be a problem bad enough to prevent starting.

Mr Fix

No electrical does not check out

I have no fuel, Main relay clicks but no power to fuel pump

If I apply 12v to pump it works but still no spark

What year, model and motor do you have?

Mr Fix

94 accord auto f22b2

At the distributor do you have power on both the yellow/green wire and the black/yellow wire with the key in the on position?

Also check fuse 39 (7.5 amp) at the under hood fuse panel. make sure it is good and it should also have power at all times.
