No crank after intake removal and coolant flush

[BrettsE30]

I just got done cleaning the intake manifold and replacing all the coolant hoses and intake seals. Now my car won't crank. It ran fine before I messed with it. Everything seems ok except I'm getting a check oil light and check washer fluid light. They are both fine. I've double checked all my conections and fuses. The motor will turn over by hand. The battery is charged and i jumped the starter and I've got nothing. What else should I try? Will it not crank if there's not enough coolant in the engine? I'm stumped and need my car back asap.

I can't think of anything that would cause the starter not to crank the engine after doing those things. If it has a manual trans. maybe you could try push starting it to see if its just your starter motor. A low coolant light won't cause starting issues.

Are you SURE you reconnected everything.

[MTechnikII]

your starter might be missing the Negative connectivity
connect a jumpercable end to the battery Neg and the other end to the little bump on the back plate of the starter then try again to start.
Let us know what hapenes

I tried to roll start it but there's no fuel in my rail yet. I tried jumping the starter and it's just making my relays click. I'm 99% sure I connected everthing but it's 12:15 am here and I'm beat. I'll try again tomorrow and let you all know what's up. It's crazy because the only thing I did even remotly related to the starter was disconect the battery. Also I totally drained the block and radiator and replaced the hoses i'm afraid it's air locked or something.

How's the battery? It has hapened to me that the almost 1 year old battery died all of a sudden, it hapened twice , with battery's from AutoZone. see if it hold s the charge.
Good luck

make sure the terminal is clean and tight..

Will a bad ground strap cause an issue like this?

I bet you have the CPS and impulse sensor wires backwards.

[BrettsE30]

Where are these sensors?

[Sagaris]

under there^ you can see both plugs side by side to the left of the dipstick.

[billybobjoseph]

Yeah it's easy to get those two switched

After all the stress it just turned out i didn't fully tighten the ground cable from the engine to the chassis. Thanks for the suggestions though i learned some new common solutions. Also i rode my bike so its all good.
