ok, i was workng on my friends 4th gen, 92 si. I took off the coil, and the therostat house to replace the thermostat. I took all the hoses off the thermo house and replaced the thermostat. i put the hoses back on the the sensor that goes on the thermo houseing. Then i put the coil back on, and tightened back down the three bolts to hold the coil on. I aslo took out the coil befor to get it out of teh way, and i disconected the gret square clip to get it out. i put that back on and made sure it clipped when i put it back in the car. Then i re attached the coil spark plug wire. And i refilled the car with coolant. The car will now not start. It turns over, and it isnt getting any spark. And the fuel pump isnt priming when the ignition it turned on. Did i trip any security systems. The car doesnt have a alarm. Does the car have a imobilizer. I have tried resetting the ecu by taking out the clock/radio fuse, and also by taking the battery terminals off. I let them be off for about 5 min and i let the fuse be out for like 10 min. Please help.

No the car doesn't have an immobilizer if there's no alarm on it. And to reset the ecu, you only need the clock/radio fuse out for 10 seconds, so it's reset.

Are both ends of the coil wire plugged in? Maybe you plugged in the coil side but not the dist. side? Also, if the fuel pump isn't coming on, that sounds like a relay/fuse. Check all your fuses, and test your fuel/main relay under the dash.

i figured it out. There was a ground wire on teh thermostat houseing that needed to be bolted back on to the houseing. It got buried when i was putting it back in and i didnt get it back on the first time. When i wentback over my work i saw it was missing and i put it back on, and the car fired right up. Thx fo the help though.
