Arrow Hard starting rebuild

Ok guys ive had my rebuild for a couple months now and I run it once a week. The builder told me I would need starter fluid for cold starts and that it was normal. I need to use the fluid for the first start (after sitting) but ti starts up everytime afterwards perfectly.

i began worrying when people on here told me their rebuilds start right up with no fluid. Im using a brand new battery. Is there something wrong with my rebuild? what could it be? I had an electrical problem before with both my alternator and main fuse. Before the fixed it i needed a jump start to start the car every simgle time. Could this be another part fo that problem. Im worried cause i paid good money for that rebuild (approx $3000 with brand new housings and a new(used) front cover and front plate). So do you all think somethings wrong?

if it has new housings it should have never needed starting fluid to start, i would say you probably have dirty injectors but that is just an assumption. start by pulling codes, run a compression test and if everything looks good then replace the fuel filter and send the injectors out to be cleaned. wouldn't hurt to double check the timing and to double check the TPS adjustment.

Anyone else got any suggestion? Ill talk to my mechanic about the injector thing and see what he thinks. I had a problem when they first installed it with the secondary injectors cause the guy who originally installed the engine used the wrong harness. To test the compression i woudl just ahve to rent a compression tester and put it in the spark plug holes right? How would i turn the rotors?

It may take some effort to start the first time (push start, etc.), but after some runtime and a few miles, it should start fine on it's own.

Used housings can make for some hard starting until things bead in, but this doesn't take that long. Certainly, if you drive the car 10 miles or so, it should start fairly easily.

It will take a good amount of time for compression to come up to spec, so it may idle weakly for the first 500-1000 miles or so. But if you are having starting problems, check compression and make sure it's not abnormally low.
