So when I spray fuel into tb it only. Backfires and nothing happens
I have changed the plugs wires cap and rotor new fuel pressure regulator
I also sprayed oil in cylinder (truck was very badly flooded)
I have spark at the plugs and can hear the injectors clicking

 

Oil in the cylinders to clear a flooded engine? That makes things worse as you now have oil coating the spark plugs along with gas.


Best thing to do, is pull all the spark plugs out and disconnect the ignition coil so it will not cause a fire. Hold the throttle wide open and crank a few seconds, wait a miniute then crank again with throttle open. That should clear a bady flooded engine.

While you have the plugs out, clean them off with brake clean and check the gap or replace them if they are old. Reinstall the plugs and verify the timing order. Then try starting. If still no start then recheck for spark and fuel pressure.

 

If oil in the cylinder is bad how do I restore compression due to the flood

 

So got the truck to fire w/ eather so I know I have a fuel delivery issue. I did have to pull tank to patch It plus while it is turning over it doesn't pull vacuum through the hose

 

Okay so I think Imight have finally diagnosed my problem. I pulled my fuel rails off to find that my injectors are plugged solid

 

If your engine is really flooded out, putting oil in the cylinder will just add to the mess inside the cylinder. Gas will evaporate usually over night but oil stays behind.

If your engine was that flooded then oiling the cylinders will be good, just leave out the spark plugs and spin the engine over to clear out the exess oil. I heard others say to use Seafoam insted of oil.

While you have the gas tank down, It will be a good ideal to purge out the fuel lines and put and new filter in too. You will have 2 fuel pumps in your truck. The one in the tank is a low pressure one that feeds the high pressure pump mounted on the frame rail right under the driver's side. The HP pump will not prime itself so you will not feel a vacuum on the line.

Best to replace the plugged injectors, but search the forums here about cleaning them.

 

Already been looking on eBay any idea on what flow rate I should run (19lb or bigger)?

 

just a thought and it dosent help with spark, but you should have a fuel shutoff relay under the dash, right around the heater on the center pass side????

 

The inertia switch is not tripped (first thing I checked) I have gone and changed so many parts and my gut told me it was the injectors so I pulled the rail and sure enough all eight are plugged (truck sat for a few years + PO never used injector cleaner in it.

 

Stock injectors will be good, unless you do major changes to the engine that needs bigger injectors(also ECU reprogrammed for bigger injectors). 19lbs I think are stock size injectors.

Also check out the fuel pump relay and ECU relay, they are near the brake master cylinder and airfilter box. I have had 2 of them donk out on me. The ECU relay was intermittant and took almost a year to find it! Only when it hard faulted I was able to track it down! What happen was water got inside them as the previous owner broke the holder the relays sit in.

 

Try changing the distributor module. Little plastic box on the distributor. My truck lost spark and died and it fired back up after changing the module.

 

I have spark and wut the PO told me bout wut had happened w/ trk I knew it was fuel related changed both relays
