Spark plugs getting wet from fuel, compression ok, not starting, timing ok, spark ok, new spark plugs, changed fuel pump in tank,

Do you have fuel pressure?

You may have to lower the tank to get access to fuel pump located on top of tank

Check all fuses first, then with an assistant, check for spark with a spark tester. if there is spark at 2 plugs, check for fuel pressure at the fuel rail with a gauge. Engines need three things to run, fuel, spark, and compression. If there is spark and fuel, do a compression test, if the timing belt jumped/broke, you won't have any

sorry if you guess and guess wrong. really, must be expensive.



ok got spark (and timing is good, timing light test)

if test fuel ( use instant start in a spray can) fails, with spark

then engine is bad, compression is checked, see near 80 not 150+ PSI , the timing belt has slipped. if not changed by the book

they slip and the engine grenades (or bends valves)



this is an interference engine, never ignore the belt.

there is an acid test order.

1 compression good.

2 spark good, and timed

3 fueling is last. (if spark plugs dry add fuel, by hand)



cant burn fuel with no compression and spark. well with EFI it cant run right with bent valves either.



here is Chad running an engine (any) with no gas tank

even his battery is dead. and has external battery. for 12v power.

a real trooper.

ive done this 1000s of times. in 60 years.

his engine only makes 80 psi (old) and still starts.

but EFI will never do that not that low. compression



the cam slips and goes retarded compression drops to near 1/2

and the valve timing is so bad, the exh opens late and pollutes the

next last intake charge. the card house falls and then the valve bend.



take if from me, nostarts are a blessing on any honda

maybe it saved your valves.? do the service on time./

If it is the 4 cyl engine, have you checked to see if the timing belt is ok and the engine has compression ?
If it has compression, and the plugs are wet, they could be fuel fouled.
I would try a new set of plugs, check the fuel pressure to make sure it is within spec, and check all plugs for spark.

Providing a accurate diagnosis is difficult. All previous advice could be correct.

I'd look into the fuel delivery issue first. The MPI (fuel pump) relay is controlled by the engine computer (ECU). If this is OK, your Check Engine Light should be off. A test with an OBD-2 code reader will tell if the ECU really is OK, and show any error codes.

If the ECU is OK, and the fuel pump is getting power, open the gas tank cap and see if this helps the car to start. (might be worn pump issues).

If you are actually getting fuel and spark, a no-start condition will generally throw an ECU error code, see above. There may be a crank or cam sensor that has failed.

The next thing to check is that the timing belt has not slipped a few teeth. This does happen. Your engine is probably a 4G64, and you MAY get away with it without bending valves. Or maybe not.

You say that it attempts but fails. If it turns over, at a normal speed and tries to start and doesn't, check that the fuel is good and new fuel. Not fuel that has been in the tank for a long time. Check the fuel filter to see if it is clogged, Check the fuel injectors to see if they are all spraying fuel and there is enough pressure in the fuel lines. Check fuel pump for proper fuel pressure. High mileage engines check for compression in each cylinder. Possible bad ignition wires or ignition timing is off. Has the engine been steam cleaned recently. Is there water in the fuel? This gives you some things to check. Good luck.

Pull out # 1 spark plug and put back into plug wire, rest on motor block so that end of electrode is against metal. turn motor over and have a finger or compression gauge in # 1 cylinder, check to see if spark occur at same time as compression (compression will blow air past finger or raise gauge). When you say it has fuel do you mean gas tank has fuel? Are you sure fuel is getting to the cylinders? are plugs wet with fuel? Does it turn over but kinda thumps or backfire (Caugh)? Check the spark and compression first. if they don't happen at same time, the timing skipped or belt broke. if all is good pull plugs and inspect, could be flooded (WET) from fuel. either replace or spray with starting fluid and compressed air to dry them. spray starting fluid into air intake if starts then stalls, try again, if same thing happens then you have a fuel problem. try these suggestions first 1/2 hr time table, hopefully sucess, if not it sure indicates fuel.

if you have spark and fuel and it is on time it should run if the compression is high enough was this car flooded really bad if so make sure your oil is OK the do a compression check dry and wet you may find when you you do your wet test that it brings the compression up enough to git the car started that would mean that your cylinders were washed out with gas causing the compression to go down

My first guss would be a fuel pump, just would have to verify that when you first turn on the ignition to crank you can either hear the fuel pump turn on in the tank or not, if you cannot hear the buzz or whine noise from the pump in the tank you need a fuel pump. Fuel pumps are a very common problem with these trucks.
