I was driving my sc400 the other day and forgot to get gas I started and went three different places. The last time I started it it started and shut right of it sounded like a lack of gas well got it home and put gas in it still doesn't start did a spark test on each side and the car is getting no spark. Wires and splugs change recently pattinum 4 splugs time and belt already done just change oil and change the fuel pump in jan I needs my baby up and running anybody knows what wrongs r had the same issues

To go aheard and rule out fuel as the issue, prime your pump. To do this, turn your car all the way to 'on' but don't crank it! Wait ~3 second then turn it off. Repeat 2 more times and try starting it again. Your coil may have just died. Though not common, it happens. Is the distributor driven by the timing belt or no?

Check your driver side coil. If good try the igniter near the driver side shock

but he's saying he's not getting spark on either side though.

Sounds to me like the igniter would be more of a culprit

so yall saying replace both igniters there right behind the engine fuse box i seen them but also the fuel pump is not coming on when u turn the key to the on position i always hear it when i turn the key to on the car was running fine no sputter no shaking it sounded like in ran out of gas when i started back up it fired a couple times then shut right off i was gonna try the fuel mod to see if that turns the pump on

cayden

and yeah not getting spark from either side and the guy i talked to told me that if the pump not coming on then the computer wont send the signal for spark dont know how true that is but i need to know dont wanna replace a bunch of stuff that dont need to be replaced

Not true at all.

Have you tried jumping it in the diagnostic box? B+ to FP should turn the pump on even if the Fuel Pump ecu is bad.

I hate to say it, but no spark, and no fuel SHOULD mean = No ecu.

Does your check engine light come on when you turn the key on?

cayden

I did the fuel pump mod today the pump turned right on but still no spark I was thinking computer was bad to r bad cam sensors and yes the check engine and trac lights are on

Hey did you ever figure this out? Im in the same boat, havent checked for injector pulse yet but I have the 12v mod so I know its pumping fuel with no spark ether bank

if not spark to either side check the igniter plug and wiring make sure its all good. If it is the check the test the igniter itself

Thanks for the reply! My buddy has the same year sc400 so I swapped my igniters into his car and it ran perfectly. Also swapped my ECU into his car and again his car ran perfectly with it.
Any suggestions as to where to look next?
