i js recently bought a Integra LS car doesnt start it gets spark, and checked every other ground wire also checked fuses. the bad it doesnt send fuel. i dont know what to check. the main relay is fine and ecu is good. i really need help guys

 

Can you hear your fuel pump prime (buzzing type sound) when the key is in the on position? Do you get pressure to the fuel rail? to the fuel filter? If you dont even get pressure to the fuel filter, then its probably your pump.

 

no i dont hear no buzzing noise or prime i thought it was my fuel pump too. but i wasnt sure it also have a fuel cut off switch but i tried with the switch on and off with key on on position still no prime

 

then check your fuel pump...easy if you dont know how the priming noise sounds like..just crank your car a few times and then pull out your spark plugs....they should be wet...if your getting fuel but the car is just not cranking then your fuel pump should still be working..if its just dead dry then your pump is dead...

 

Yar, waht he said above. But if you have a kill switch, sometimes the connection goes bad. Check your wiring and if anything, try it without the kill switch and if it still doesn't work then you may have a bad fuel pump.

 

how did you find out your master relay was fine?

 

i put it in my brothers car and everything sounded rgiht

 

do you at least have spark?

 

yeah it get sparks.

 

your main relay will also tell you if your getting fuel....try switching it from your brothers car to yours..see if that could be the problem...i tried it on an accord before...it would crank n spark but no fuel...heard the fuel pump priming so did research on HT and some say that could be the problem..after i went and got a used one for 3.00 i finally started to get fuel and got the biotchh running....

 

well guys thanks for all the help. i figure out one problem i got the fuel pump to prime up. the last owner had a ghetto wire up for a fuel cut off switch so i js took that out and connect the original wires back togethr and it primed up. my motor cranks but still dont start up. i smell fuel in the engine bbay area well any advice would help guys.

 

now that your getting fuel. check your distributor. I beleive Autozone checks your ignition coil for free. could also be a bad cap or rotor...check your spark plug wire orders just incase you put them in the wrong order. another thing you can check is jack up your car and turn your crank pulley counter clockwise until you line up your tdc marks to make sure you didnt jump a tooth

 

bump

 

okay so i guess my car is getting no compression so i guess the bottom block is bad. so im taking out the motor and droppiing another LS i have on the side. thanks everyone for helping

 

it just all of a sudden loses compression?

 

dang, from no spark..... to no fuel.... to no compression..... so basically you just had AIR. you started out 1/4 of the way from cranking.

 

the motor just cant all of a sudden have no compression....checking your compression is only accurate when your car is at normal operating temperature...im sure if all your cylinders just lose compression then your just not doing something right...

 

check your ecu fuse... that sometimes goes out at the weirdest times... its in the engine bay

 

well i never had the car running i bought the car for 2gs straight body, he told me the car ran and stuff but anyways i already like 80% percent done on taking out the motor.

 

if the motor is flooded with fuel it will wash the cylinders and give you low compression

 

need help really bad i just replaced the raditator bc the bottem blew then my top rad hose blew next day replaced that and thermostat then a rad hose under the injections blew replaced that and now my hoses feel very very hard anyideas ??????

 

what injections? are you overheating? if not then you should be fine or try bleeding your coolant. mine are pretty hard also but drives normal..car temp rises to normal...so i just leave it

 

what if it doesnt start either? then thats going to suck
