Mint93

I have a 90dx and swap a 93dx motor into it and reused the 90 stock intake manifold. The engine turn over,getting spark and getting fuel.Hower I pulled the plugs and it looks like only one of the spark plug is getting fuel. I don't know if the 93 motor was running before. What can it be?
Thanks

make sure you put the dist on properly, you can install it 180 degrees out. other than that it could be anything, why do all that work if you didnt know if the engine was any good?

you have 2 injectors, if they're spraying all the cylinders should be getting fuel cuz it's a TBFI setup. I agree with the 180 degrees dizzy...

car tech

thr dizzy will not fit 180 degrees cuz the slot is not even.

if u have gas and spark it will run if the timing is rite.

set ur crank/ cam timing first and and make sure ur firing order is rite and check ur ground under the thrmostat housing.

good luck

car tech, what we mean by 180 degrees out is that the dizzy is installed with the #1 cylinder at TDC but on the exhaust stroke instead of the compression stroke. I've done that before once, and all I did to fix it was switch around the order of the plug wires.... it wasn't on a honda though.

car tech

if it was installed 180 degrees it backfire when u try to start it

that would mean the cam wouldhave to be out by 180...

since the dizzy only connects one way round to the cam shaft... you can't install them backwards from each other.

like I said it wasn't a Honda... it was on my old Suzuki Samurai. I just remembered I never told the guy about it... hope he figures it out.

Thanks for all the help guys.
Still not starting. Turning over,getting spark. getting fuel to the fuel rail but only one spark plug is getting fuel. If the timing is off could it cause this problem? I took one injector off to see if it was spraying and it wasn't.I changed the intake and the injectors and it's still the same.

check for signal at that one injector... it's possible the injector harness is messed up!! to test, you use a noid light... I suppose you can also use a voltmeter to see if both injector plugs are getting proper signals. if there is no signal, go back to the ECU pinout and check that the ecu is sending a signal to the pin. if it is, then your harness needs work, so just run a fresh wire from the ECU to the injector. if it's not sending a signal to the one injector, but it is to the other, you prolly need a new ECU.

Do you think it's the timing?

can't use a olt meter unless it can check frequencies
