Lost all power on the highway, now no start??

[boostingsx98]

I have a 98 gsx with a 7 bolt evo motor. The mods are fpr, 780's, 255, 50 trim, intercooler and dsmlink. My problem occured yesterday when i got on the highway coming back from a friends house. Everything was working great until suddenly i wanted to give it a little gas to get infront of another car and it would not go, it seemed like it just suddenly lost all power. Now it will not start. I checked fuel and spark and its all there. The timing is correct as well. Im stuck with no other ideas of what could have possibly went wrong. Any help would be greatly appreciated.

Thanks

Can you connect to the ecu?It will crank but no start?

Fuel pump? Just 'cause it's circulating some gas through the rail doesn't mean it's actually moving enough gas to run the car.

Check the intercooler piping. A piece may have come apart, this happened to me before.



Also, what do you mean by 7 bolt evo motor?

Check fuses. My rewire for the fuel pump grounded out and blew out the fuse just this week.

Evo IX MIVEC engine, probably.

Yes i can connect to the ecu. I also pulled the feed line coming from the fuel filter to the fuel rail and cranked the motor a few times and there was a steady stream of fuel coming in. So im not sure what else it can be??

I mean Evo III motor.

check your fuses, and does the car crank? or nothin happens when you turn the key over?

I would double check the timing I had the same problem with my car I lost all power and came to a complete stop and I had a big boost leak I would check for that as well as you can lose lots of power from that

 

[Technoklipz]

You could check the ecu and then any extra wires that have been wired into it. One of them could have came disconnected and cause your car not to run. I had this happen a few years back.

I would also check your crank sensor if its bad it will case your car not to start

 

[boostingsx98]

Well i just went out to the car and i primed the fuel pump through dsmlink and i checked the fpr gauge and it was at zero. So i swapped it out for a stock fpr and still no start. So i assume its not the gauge but the actual fuel pressure. I pulled the feed line that goes to the fuel rail and cranked the car to double check if fuel is flowing and indeed it is. I am stumped.... any ideas??

 

[dsm92talonboost]

is the car crankin and not starting? or exactly whats going on? did you check the fuses?

also another thing since you checked that you are getting fuel, check to make sure your getting spark in every cylender!

 

[roybatty]

The "is it cranking" question +1. It could be a timing belt/pulley. All routine maintenance up to date?

The car is cranking but no start. I checked spark on all the plugs, fuses and maintenance has been kept up. I am assuming is has something to do with the fuel pressure because my fpr guage reads zero the whole time even when i prime the fuel system. Could it be the 255 i just put it in about 2 weeks ago maybe something could be leaking?

If your priming the pump I would think you should def. be seeing more then 0. Could have popped a fuse possibly? If you were leaking I think you would smell gas like woah.

 

[dsm92talonboost]

check all the wiring from the fuel pump, make sure you have a good ground so your gettin full potential from it,you said when you pulled the fuel rail you were getting a good stream right? well just cause your gauge is broken dont mean your not gettin pressue, especially when you said you put the stock one back on and it did the same thing

 

[roybatty]

Need to verify air, fuel, spark, compression, and ECU. It sounds like you are getting fuel, verify plugs smell gassy. You can have someone check for spark as you crank. If its cranking/timing good, you have compression. That leaves MAF and ECU to focus on.

 

[dsm92talonboost]

car will still start with out a maf, just idle like poo and not drivable haha

May be a good time to upgrade intake ($$) or get a working used one.
