Car aint startin now

well today after school i pulled into my moms store cause it was runnin alittle hot. well to find steam rolling out the hood i blew the coolant line from back of the engine to the back of the water pump. no biggy right. well i tore it down and put on a new hose. went to start,, nothing fought with it there for couple hours finally got so pissed called and got it towed to my house, tore it apart cleaned it up make sure everythings good. still nothing it will start and trying for ever and acts like its only running on one rotar. no power at all. well pulled brand new plugs front ones look ok like there firing good but the back are wet??? What is going on? anyone have an idea i dont see how a blown water hose could cause this. im pretty sure it didnt over heat my gages dont seem to work perfect but this motor has those heat tabs on it and there still good so i know i didnt get hot enought to melt them. but please help out on this i just started drivein this thing now the funs over. the cars a 87 turbo just got the motor in it not but 2 weeks ago.

Define "Wet". Wet as in soaked in Gas or wet as in soaked in coolant. If you are not sure, fill up your radiator and bleed off all air. Leave the radiator cap off, pull the EGI fuse, have someone turn the engine over. If the coolant shoots up, you blew a water seal, rebuild time. If not, you are ok, and you seem to have a bad injector and/or low compression. Waiting to hear.

Also guys my primary injector connectors shattered, the plastic ends that connect to the injectors. so im using just indival connections to the to connections on the injector so instead of 2 plugs to the 2 injectors i have 4 wires and i connect each one. Only thing im wondering since it was bare wire there could that coolent that went everywere grounded them out and some how screwed up comuter or something else.

Also could any of this be caused by a messed up igniton switch? mines screwed up right now i start it by turning the switch to start and pushing a button that triggers the starter to crank. cause turning the key to start doesent crank the starter. but its been starting every time for almost 2 weeks i dont see why it wouldent now

sounds like it's just flooded try unflooding trick. if you think it's the wires to the injectors just test the circuit with a volt meter

Well, just got back on here. took voltage of the wires going to the front and rear primary injectors, With ignition off, both front and rear showed o volts, with ignition on, front showed 10.4-10.5 volts, the rear showed 4.9- 5.0 volts. Does this sound right? Please any more help would be greatly appreciated
