like the title says i have a problem starting my car it cranks but hardly and i need ne kind of input at this time. i just swapped this motor into my car and of course it won't start(always something) my timing is correct double triple checked(but timing wasn't correct athe first couple days i tried starting it so i went by process of elimination to figure out that was one of my problems) i changed my cap and i have good spark from the coil and the spark plug wires.i have a aftermarket link sys ECU(integra link ECU) tat won't communicate with a scan tool(it did before but didn't the last time i hooked it up) i have the grounds connected on the thermostat housing . i have plenty of fuel getting into the cylinders. Triple checked the firing order .All good there.when i crank the motor it acts like it wants to kick then goes dead and the Voltage drops to 8.7 (almost sounds like a bad battery)ive tried to jump it with another car and ive charged the **** out of the battery(the cranking sound goes like this ....dah dah dah bleh... dah dah dah bleh ...dah dah dah bleh)like a dead spot or something. i have at least 145 plus all across in compression . when i diconnect the coil from the cap the car spins over freely when cranking no dead spot . (weird)someone told me to check th esensors on the manny so i did went thru all the wiring and everyhtnig seems to be ok (btw the car just had almost the same motor in it and i had no problem)it's an ls vtec
9:1 pistons
eagle rods
b18c (p72 head)
valves
skunk2 (springs and retainers and cams and cam gears)
msd coil and cap and wires
vtec oil pump
ls timing belt and water pump
t3 turbonetics with intercooler
fuel regulator
etc............................please ne input is much appreciated

 

how many threads are you going to make about this?

you say your getting fuel, how much fuel are you getting? is it dumping fuel without stopping?

put the ecu in a car that starts fine and see if that ecu works in the other car or not. also sounds like you drained the battery.

i would look into the ecu since you mostly checked everything.

try putting a stock ecu in your car. im guessing your using obd2? does the check engine light come on?

 

yeah sorry bout the threads im just anxious to get it running . but yeah the light comes on when key on and goes out like normaland comes on when cranking but my only problem is i don't have the stock ecu

 

obd 2 yes

 

oh teh only thing i forgot to mention is tat before i did the swap my alarm worked fine but after connecting my battery back up again the alarm didn't respond to the key pad (i changed the battery out of the key pad) so i disconnected it from the ignition so now no alarm!

 

swapped out my dizzy and it fired right up
but of course ls vtec sux cause it smokes and the rings i put in arent sealing properly

i feel ya. ive got pistons that should be 11.6:1 my lsv and i get worse numbers than u with your 9:1 ... perfect 145 psi across the board.

 

yeah but number one is like at 105 on the third crank so i am quessinng it's the used pistons i put in it i am beginning to hate lsvtec this is my third lsvtec ive had problems with the rings on 2 of em
