car cranks but will not turn over fuel pump good plugs and wires are good not understanding the prob changed main relay did not help car was running fine only prob was bogging at 4,000 rpm please help

 

check that your crank and cam turns while cranking.. Have you checked for spark? fuel pressure? You can hear the pump prime but theres not enuff fuel pressure

 

ya nova, sounds kinda like what was happening to my accord when my fuel pump went out. Clicks from the relay were good, but no pump - or weak pump.

 

another thing - inside the distributor I had to replace the igniter, behind the rotor. Mine wouldn't start for some reason - it probably arched on something and shorted it out. took 15-20 minutes to change, so u might wanna give that a shot too.
good luck

 

Cranks All Day But Not Turning Over.... No Spark Please Help!!

I'm starting to get frustrated and I'm not sure where to go at this point.
1996 Honda Accord LX 5 Speed
JDM F22B SOHC Non-Vtech 35,000 Miles. Used only Block and head. Everything else was transferred from previous F22B2 Engine Including Oil Pump With Crank Sensor And Old Dizzy. Old Engine had 168,000 miles on it I blew a Rod Bearing.

After swap car ran perfect with no Check Engine Lights on. Recently after hitting 1,000 miles on the swapped Engine the light came on. I took it back right away to the mechanic and he check the code and said it was oxygen sensor bank 2 and that I would be fine driving until I replaced that. The very next day The engine died while driving. First the tach jumped up and down then it just died. I was traveling at about 45 mph. The engine will crank all day but will not turn over. I got the car towed home and the next day I started troubleshooting. First checked for fuel my removing the main line to the rail and cranked plenty of fuel was coming through. I ruled out the fuel pump and fuel filter. I next checked for spark and found the problem. No spark out of the wires or the coil. I removed the ignition coil and took it to AutoZone and had it checked. He said it was fine. I reinstalled the ignition coil. I checked the 7.5 ECU Fuse it was fine as well.. I then purchased a new main relay just in case and still wont turn over. I pulled off the valve cover cap and the timing belt is fine. Next I pulled out the DIZZY for inspection and there was oil inside and rotor looked bad. So I rebuilt the dizzy. I replaced the Ignition Control module ($49.99 AutoZone).
I replaced the Dizzy shaft Inner Seal and and outter o Ring ($14.99 EBAY) I put the dizzy back together with new rotor (19.99 AutoZone) And new Cap (16.99 O'Ryelly) The only I didn't change is the TDC sensor inside the Dizzy because of Price. Available online only between $160.00-$230.00. (Price of new Dizzy) I installed my Dizzy last night. Still the Engine wont turn over. Whats Next?? Crank Sensor?? or perhaps when my mechanic installed new timing belts with with swap he left them too loose and it jumped timing?? Should I go ahead and buy a new ignition coil anyways just to be sure?? Will a bad TDC sensor stop the Engine from turning over? Somebody please help. I welcome all advice before I start spending more money.
Thank You.

 

Yes that can cause a no spark......also since the engine was just swapped, check the main gorund on the end of the TB to be sure it is clean and tight.

 

Thanks for the info.
OK so The main ground connected to the throttle body. I have not checked that. Where exactly is that?
