Hey guys I just purchased a built boosted gsr integra for dirt cheap because the body is hell and the interior needs alot of work. The car ran fine I have receipts with close to 10grand into the motor. The guy got sick of it and sold it. current problem with the car is that it starts and dies right away? where do I start im sort of a noob

thanks

 

fuel pump or main relay...

 

he says the fuel pump is new and he thought it was the main relay

back again with the same issue, I had the car running perfect for 3 days took it in to get valves adjusted on my way home from the shop it died on me and when I went to start it it shuts off right away. Now I get the car to idle if I wiggle the tps sensor but once I go to give it throttle it dies on me. Please help me!

 

It seems like this could be a number of little things to check. Do you have any check engine lights? Since you mentioned wiggling the TPS to get it to idle, maybe start with that. I would pull the plug off, make sure it's not corroded at all (getting a good connection) and re-calibrate it to make sure it is within spec. If you don't know how to do that, there are several threads floating around if you search "calibrate TPS". It invovles loosening the screws that hold it to the throttle body, these will have to be notched if they have not already because they are tamper free screws, and then setting it within the specific voltage range of .48-.50 closed throttle, and 4.5 volts wide open throttle. If this doesn't solve your problem, maybe the TPS is bad and could be replaced and re-calibrated with a known working one (if you have a buddy with a honda around you).

If it turns out that the tps is not your problem at all then you need to start looking else where. Did you try a different main relay yet? You say it starts EVERY time but dies shortly after wards? Sometimes, when the main relay is starting to go, it will work at first but when it warms up after running for a bit, it will stop working. In your situation, it could be the main relay, but it seems like if it was it wouldn't continue to start the car every time and then persist to shut off the car. It would more then likely just not start the car at all or be more miss than hit. It would be wise to just go through a list of things to check that are important. Make sure your grounds are all good, check the thermo-stat ground for good connection. Check the map sensor and make sure the plug isn't corroded; normally if the map is getting a bad connection it will just run really crappy, but will still run. Maybe try a different distributor, check the spark plugs, etc. It may be the chip or ecu, sometimes they go bad or aren't getting the proper ground.

When you turn the key to the on position, before cracking, listen for the main relay to click and the fuel pump to prime. If you don't know the sound, listen carefully, you should be able to hear a click noise come from the relay area, and also a distinguished sound coming from near the back seats (pump prime). Go through some of this stuff and report back. Good luck.

EDIT: Did the guy you bought the car from ever get the car to run well or did he just give up on it because he couldn't get his setup to run right? The chip or ecu may be the culprit.

 

I had the car running fine for 4 days and he had the car running fine and then when this issue came up he gave up, the ecu was retuned a few months ago and a 3 bar map sensor was installed. I just replaced the spark plugs but it was running rich today so I am going to check them out again tommorow they could have gotten bad I was told. and yes the car will start every single time and die again, unless my buddies wiggeling the tps and then itl stay idiling but once i give it throttle it dies, last time what fixed it was a boost leak and a vacume line that was plugged up. I will check all the other things and let you know

 

went in the car today and it started right up and ran perfect... weird

 

Sure sounds like a TPS issue, why not just replace it with a new one, or test with a known working one?
As mentioned carefully inspect the connections. 94
