Hello everybody,
im sure ill get my *** chewed because this is my first post on here and im noobish when it comes to mazda's..

So i have grown up on hondas, i know everything about them and one day i decided to get this Miata.. picked it up for 1500 bucks. It is a 1995 1.8 liter with the lsd rear end. the only mod it has is an ebay, obx fuel rail.

i drove it home, it ran good, but seemed like it had a lot of power loss.
i drove it back and forth for school for about a month and it drove decent. seemed like is had power loss still.. so one night i pulled into the garage. threw the codes up. and it showed tps sensor and egr valve both vacuum and vent.

I replaced the tps sensor and never fucked with the egr, because i had plans to just do egr delete. so i replaced tps and it would not start.. so i put back the other tps and once again no start. cranks good. doesn't start.
YES it does have spark, fuel, air etc. it has the basics. i just cant figure it out.. so i checked timing, its good. i replaced maf, iacv, all vacuum lines, fuel injectors(because they were bad) and still no start.. so i let it sit in the garage a few days. it started right up about three days later. i let it run. shut it off and once again, no start. :( somebody please help me!! im sorry about the super long storyline bull ****. just trying to give you guys everything you would need to know... and sorry that i dont have a signature yet!

 

its probably flooding.

pull a spark plug and check next time

 

i forgot to mention that.. it is flooding. but i mean i dont know how. like do you think the aftermarket pos fuel rail could make it flood?

 

stock fpr? is it working?

 

i dont really know how to test it.. but i did replace it with a different one. but its doing the same thing.. so i really dont know man.. im sorry for being such a noob lol

 

What injectors are in it?

When you checked timming did you jump ten and ground?

 

You say you replaced the fuel injectors because they were bad. You could have either put in a bad one or pinched a wire to ground holding it open.

 

i replaced them with factory tan tops.
and yes when i checked i pinned ten and ground.

 

Welcome to the site RICHSCHUCK, thanks for joining up!

 

UPDATE. so i pulled everything apart. and it was off timing by 2 teeth.. so i fixed the timing. it is 100 percent perfect.. BUT. the cas sensor is loose and out of wack so i cant really get ign timing perfect.. but it is still flooding. i do have spark to all four cylinders. but i dont really know if its enough spark. i feel like on hondas the spark is a lot brighter.
when i check the spark its a really dim orange..? is that normal?

 

you know anything by chance... i really need a running and driving car..

 

i also pulled the fuel rail off and liet the injectors spray as someone was cranking. it looks like everything is perfect. the injectors aren't stuck open. it has perfect pulses.. so that would mean its a spark issue right..?

 

Dude if your CAS is loose then it's no wonder it won't start. Did the PO lose the bolt or something?

 

You need to get the CAS sorted out, your ECU needs it to control spark...

Also, this should go without saying, but you've cleaned/replaced the spark plugs after all the flooding, right?

 

yes i have replaced te plugs after all of this.. and am i really that stupid that its not starting cuz the cas is loose.. if im really that stupid than i am a super noob..

 

Its always the small details that will get you. Miatas are CRAZY simple.... its either gonna be VERY obvious what the problem is, or it will be some obscure off the wall problem that you wouldnt think of

 

Welcome to the site. Couple of things here.

Why is the CAS loose???

Why would you bother trying to get something working properly when you KNOW something is loose? Why don't you fix it? The CAS controls timing. You really need to do some of your own research and reading. If you don't know what something is, what it does, and why it may or may not be loose you need to figure it out for yourself. These are simple things. You know everything to know about a honda, but not a miata. They're not much different except the engine sits the right way. You have no excuse not to know.

Take that stupid aftermarket fuel rail off and put an original one on, with an original working FPR for that year car you have. It's probably not the reason it's flooding, it's probably flooding because of the timing, but this couldn't hurt.

Does it still have codes?

 

Agreed with the rest, fix the loose CAS and welcome!

 

Like others have said. Problems on these things are typically simple or obscure. Since you know the CAS is loose, and it can cause a problem like you're describing, snug that thing down already. Even if it doesn't turn out to be the only problem, at least you can rule it out.

Welcome aboard.

 

the codes it is throwing is egr related. and i didnt think egr could make a car not start..
it is throwing,
egr/ vent
egr/vaccum
and i had the cas loose to adjust ign timing..

and on a side not, i dont know EVERYTHING about honda's lol
